Product Overview

Graphene Quantum Dots (GQDs) are a novel zero dimensional nanomaterial composed of graphene lattice and sp ² bonded carbon nuclei, with abundant edges and wide surface area. Its lateral size is usually less than 30 nm, and the number of layers is below 10. Due to their unique structure and properties, GQDs have demonstrated extensive application potential in multiple fields. There are various methods for preparing graphene quantum dots, including top-down method, bottom-up method, solvothermal method, and mechanical exfoliation method.


Technical Parameter

Luminous color:White light

Fluorescence quantum yield :23.66%

Luminescent solvent:DMF

Product Features

Stable photoluminescence properties: GQDs exhibit strong fluorescence, non-zero bandgap, and good water solubility, making them outstanding in optoelectronic applications.

Low biological toxicity: GQDs have good biocompatibility and low biological toxicity, making them suitable for biological imaging and tumor treatment.

Multifunctionality: The fluorescence properties of GQDs can be effectively regulated through doping, surface modification, and other methods, which can be used to construct carbon based light-emitting devices and other composite materials.

Application Fields

Light emitting devices: Due to their excellent photoluminescence performance, graphene quantum dots are used to construct white LED devices to improve luminous efficiency and color reproduction ability.

Photoelectric sensor: Graphene quantum dots perform well in photoelectric sensors and can detect various environmental parameters.

Fluorescence analysis: Graphene quantum dots are widely used in fluorescence analysis due to their high sensitivity and low background signal.

Biopharmaceuticals: Graphene quantum dots have good biocompatibility and low toxicity, and can be used for biological imaging, drug delivery, and cell labeling.

Energy equipment: Graphene quantum dots have attracted much attention in photovoltaic cells and photothermal therapy due to their efficient photoelectric conversion performance.

Simple gold colored hoops
Color: Yellow Gold, Color: Yellow Gold
I love the color of these hoops. They are a nice light gold color that is not too yellowy, and not brassy. The three hoop designs in this set are simple but pretty. I love the braided hoop, it is my favorite of the three. The largest hoop has tiny cubic zirconia stones set into the hoop. Nice idea, but they are so miniscule that you don't get any sparkle effect, and they just basically give the hoop a little more texture. Some of them take a little more fidgeting to close properly, but the hinges on all of the pairs open and close well and seem nice and solid. They don't cause any irritation to my ears. They come in separate cellophane bags inside an unbranded dark grey jewelry bag. I'm happy with these earrings.

Lots of variety
Color: Yellow Gold
This set of earrings are a nice set of varying sizes of hoops. Each set has a different pattern and diameter. They are are posts that the hoops hook onto so there's no backing to loose and they self lock. I find this style much easier to put on than the huggie style earrings. This is a great value and you can give this as a gift of three pairs or split up the pairs and give them as separate gifts. They come in plastic bags with no gift box.

Dainty and well-made
Color: Yellow Gold, Color: Yellow Gold
These are the perfect size for dainty stylish gold jewelry. Minimalist jewelry is really back in style and these earrings provide a great variety of options at an amazing price! I have a few pieces from Amazon essentials and I’ve been happy with every single one, they don’t turn green on my ears, and I have swam and bathed with them without any issues. I’ve had trouble with some hoops because the clasps wear out after a while, but these seem to be holding up very well. My favorite pair of the three is the chain one, it’s not the picture because I am wearing them!

Not for those with thicker earlobes
Color: Yellow Gold
This is a really cute set with perfectly sized hoops! They look so chic and can complement so many different outfits. The gold color is very nice and shiny. The only downside for me is that if you have thicker earlobes like I do these might not fit or feel very tight. Also the part that goes into your earlobe is not a regular size rod and gets thicker so if your piercing is tiny these might not be the most comfortable to wear.
