Name: Carboxyl Graphene quantum dots

Product Overview

Graphene quantum dots (GQDs) are nanoscale fragments of graphene with unique physical and chemical properties, such as quantum size effects, edge effects, etc. By specific synthesis methods, the size, shape, and luminescent properties of GQDs can be controlled. At present, Xianfeng Nano's available quantum dots are divided into graphene oxide quantum dots, graphene quantum dots, semiconductor quantum dots, etc. Customers can choose according to their experimental needs. The preparation methods of graphene quantum dots on sale are divided into bottom-up and top-down, with different colors of luminescence available, such as green light, blue light, red light, and white light. Meanwhile, graphene quantum dots with different functional groups can be selected, which is also helpful for later modification coupling. In addition, nitrogen doped and boron doped graphene quantum dots can be selected. At present, the applications of graphene quantum dots are mostly focused on fluorescence imaging, nanoadditives, antibacterial, and biotoxicity.

Product Features

Uniform size: The size of hydroxylated graphene quantum dots is usually between 1-10 nanometers, and their distribution is relatively uniform, which provides a basis for their application at the nanoscale.

High dispersibility: Due to the abundant hydroxyl functional groups on the surface, hydroxyl functionalized graphene quantum dots exhibit good dispersibility in aqueous solutions and other solvents.

Rich reactive sites: Hydroxyl functional groups provide abundant reactive sites for hydroxylated graphene quantum dots, making them easy to connect or modify with other molecules or materials through chemical reactions.

Excellent optical properties: Hydroxyfossilized graphene quantum dots have efficient fluorescence properties, high fluorescence intensity, and long fluorescence lifetime, which makes them potentially valuable in fields such as biological imaging.

Good stability: Hydroxyfossilized graphene quantum dots exhibit excellent stability in extreme environments such as high temperature, acidity, and alkalinity.

Very pretty
Color: White
This is a very pretty earring tree and not too big. Earrings show up well. Only downfall is there is a slight tipping forward of the actual tree. You have to wiggle it around to make it totally straight and just tightening the nut underneath is not enough, it takes some adjusting. That is not enough to reduce the rating since it is so pretty and the tray below is great.

Very pretty and fairly sturdy
It comes unassembled but is easy to put together. I will be adding a bit of glue so it does not turn after assembled but it doesn't affect the functionality. It looks very nice and holds a lot of earrings. I'm using it for a few companion necklaces as well. The tray is nice for bangles and rings. I really like this tree!

Cute but not the sturdiest
Color: White
It hold everything well and looks really nice on my dresser. I like that the variations in the leaves allows for me to hang things of varying size up in a way that’s cute and accessible when I want to wear it. I like having all my jewelry visible at a glance. The base is a really light weight wood and so you can’t screw the top super tightly just because the wood wouldn’t hold up to that very well. That means that the tree may lean or spin a bit if you’re grabbing your earring and it’s base from one of the leaves. There’s no fear of breakage, but just not the ideal experience. So it’s not the sturdiest. It doesn’t really need to be to do what it does, but that’s the one thing I wish could be improved about this display.

I love this!!
I struggled to put it together - I had to use pliers and REALLY PRY to get the nut off in order to screw it to the base. But once I did, I am super happy with this. It's pretty and has a lot of room for all my earrings. I also put necklaces and bracelets in the base. The downside other than how hard it was to put together is how wobbly the tree part is, but I think if I tightened the screw, it would be fine.

Awesome jewelry tree
Color: Black
The design is attractive and the holes for earrings are placed perfectly. I also have several necklaces hanging on the branches. The tray underneath the tree is perfect for bracelets and watches.I feel this is a unique design. I did attach washers above and below the tray on the screw to secure the tree better- love it!!!
