Product Overview

Upconversion nanoparticles (UCNPs) are nanomaterials that can convert low-energy light into high-energy light. They are composed of inorganic nanocrystals doped with rare earth ions and have unique upconversion luminescence properties. Rare earth upconversion luminescence is based on the 4f electron transition of lanthanide rare earth ions. Currently, the common upconversion luminescence mechanisms can be summarized into three types: excited state absorption, energy transfer upconversion, and photon avalanche.

The preparation methods of upconversion nanoparticles mainly include coprecipitation method, high-temperature pyrolysis method, hydrothermal method, solvothermal method, sol gel method, etc. In order to widely apply UCNPs in the biomedical field, in addition to improving luminescence efficiency, it is also necessary to functionalize their surfaces to enhance water solubility and biocompatibility, and achieve multifunctionality. The main surface modification methods include ligand exchange (PEG, PEI, etc. with - COOH, - NH2 groups), ligand oxidation, ligand adsorption, layer by layer self-assembly, and silica coating.

Most of the rare earth doped ions in the nuclear nanoparticles are exposed on the crystal surface, which is prone to non radiative energy transfer with the external environment, leading to fluorescence quenching and thus reducing the upconversion luminescence efficiency. The most commonly used method to reduce this quenching process is to wrap an inert shell layer on the surface of doped nanocrystals to form a core-shell structure, which confines the luminescent ions in the internal core. The shell layer increases the distance between the luminescent center ion and the external environment, effectively reducing energy transfer and thus increasing the luminescence efficiency. At present, the most commonly used method is to modify the shell layer in the previously synthesized nuclear layer structure that is the same as the matrix material, such as NaYF: Yb, Er@NaYF4 NaYF4: Yb, Tm@NaYF4.

Product Features

 

Colorful luminescence: By changing the type and concentration of rare earth ions doped, multi-color luminescence from visible light to near-infrared light can be achieved.

Stokes shift is large: Stokes shift refers to the difference between the emission wavelength and the excitation wavelength. The Stokes shift of upconversion nanoparticles is relatively large, which can effectively reduce self absorption and background interference, improve luminescence efficiency and detection sensitivity.

Good photostability: Upconversion nanoparticles have good photostability and can maintain stable luminescence performance under long-term illumination.

Good biocompatibility: Through surface modification, upconversion nanoparticles can be coupled with biomolecules (such as proteins, antibodies, etc.) to achieve biological labeling and detection.

Non damaging to biological tissues: Its excitation light source near-infrared light (980nm or 808nm) has strong light penetration, almost no damage to biological tissues, and no background fluorescence.


Application Fields

Biomedical: Upconversion nanoparticles can serve as biomarkers for cell imaging, biological detection, drug delivery, and other applications. For example, coupling upconversion nanoparticles with antibodies or biomolecules can achieve targeted labeling and detection of specific cells or biomolecules.

Optical imaging: Upconversion nanoparticles can be used for deep tissue imaging, such as in vivo animal imaging. Due to its longer emission wavelength, it can penetrate deeper biological tissues, reduce tissue scattering and self fluorescence interference, and improve imaging clarity and contrast.

Photocatalysis: Upconversion nanoparticles can convert visible light into ultraviolet or near-infrared light, thereby broadening the spectral response range of photocatalytic materials and improving photocatalytic efficiency.

Solar cells: Upconversion nanoparticles can be used to improve the efficiency of solar cells. By combining upconversion nanoparticles with solar cell materials, low-energy photons can be converted into high-energy photons, increasing the absorption and utilization of solar light by the cell.

Good Plug
Purchased this from Amazon for convenience and it arrived quickly so I was satisfied. If I order the oil and filter for mower at the same time it saves me time and I have them delivered to my door for the mower tune up.

This card is awesome!
Style: Prime Visa
I’ve been using the Chase Prime Visa card for over a year, and it’s become one of my favorite credit cards, especially for anyone who regularly shops on Amazon or Whole Foods. Here’s my personal take based on firsthand experience: ### Pros: 1. **Generous Cashback on Amazon/Whole Foods Purchases**: The card offers 5% cashback on Amazon.com and Whole Foods purchases if you're a Prime member. Since I do a lot of online shopping and grocery runs there, the cashback adds up quickly. Every couple of months, I have enough cashback points to significantly reduce my bill, which is super satisfying. 2. **Solid Rewards for Everyday Spending**: Besides Amazon and Whole Foods, the card gives 2% cashback on restaurant, gas station, and drugstore purchases. I find this feature great since I often fuel up and grab meals on the go, and it's nice knowing I’m getting something back on those purchases. 3. **No Annual Fee (with Prime)**: Since I’m already paying for Amazon Prime, having no additional fee for the card is a bonus. It's like getting extra perks from Prime without paying more. 4. **Redeemable Points**: I love that the cashback can be used directly on Amazon for purchases, but I usually save my points to cover larger purchases or statement credits. 5. **Travel Perks**: While I haven’t used it extensively, the card does offer some decent travel benefits like no foreign transaction fees and access to some travel protections, which can be useful for international travel. ### Cons: 1. **Requires Amazon Prime Membership**: The biggest downside is that the card is only valuable if you're already an Amazon Prime member, which costs around $139 a year. If you’re not a frequent Amazon shopper, the perks might not justify having the card. 2. **Limited Categories for High Cashback**: Outside of Amazon and Whole Foods, the cashback categories aren’t as high (2% for gas, restaurants, etc.), so if you're looking for a broader range of high-reward categories, this card might feel limited. 3. **Amazon-Heavy Focus**: While I enjoy the Amazon-focused rewards, someone who doesn’t shop there often might find the card’s benefits less compelling. If you’re looking for more flexibility in redeeming points for travel, the Chase Sapphire line might be better suited. ### Overall Verdict: If you’re an Amazon Prime member and do a lot of shopping on Amazon or at Whole Foods, this card is a no-brainer. The cashback rewards are generous, especially compared to other cards. However, if you’re not an Amazon or Whole Foods shopper, there are probably better options with broader rewards categories. For me, the Chase Prime Visa has been a great addition to my wallet, primarily for its ability to consistently give me back a portion of what I’m already spending.

Great card for Amazon purchases, read the fine print people!
Style: Amazon Visa
Seems to be a lot of griping from people who don't understand how to read the fine print and use common sense. This is basically a store card/loyalty card Visa like many retailers offer. That being said, the interest rates are always high on these types of cards. Deal with it. Don't carry a balance. "Instant" credit approval is assumed if there is nothing in your account that needs reviewing. If you need the $30/$50 immediately to make your purchase, maybe you should rethink what you are buying. If you're getting this card, I'll bet you'll buy something from Amazon again and be able to use that gift card before long anyway... Card Pros: -1 point=$1 spent. $1 spent at amazon gives 3 points (3%). $1 spent elsewhere gives 1 point (1%). For me, I like it simple, no point-to-dollar conversions like the citi card. -Card is by Chase. May be a pro/con here, but if you already have Chase accounts, this card will show up after a couple weeks in your chase.com online account. Easy to manage and make payments straight from your checking account. -No annual fee. -Redeem points at any time for anything sold by Amazon. Yes there is fine print, marketplace purchases can't be funded with points, neither can subscribe and save. Boo hoo. Read the terms and you won't have to post 1 star reviews whining about what's explained in the fine print you didn't bother reading before handing over all your personal information. :) Card Cons: -Interest rate is high. As stated above, these types of cards always have high rates. My condolences if you are under the assumption that a 13%+ rate is a good rate. Bottom line- read the card's terms and conditions before applying, understand the rewards and how to use them, pay your bills on time, and you'll wind up with some nice rewards points to use on something fun from Amazon.
