Quantum dots are quasi-zero-dimensional nanomaterials composed of a small number of atoms. Roughly speaking, the dimensions of the three dimensions of quantum dots are all below 100 nanometers (nm), and their appearance is like a very small point-like object. confinement effect) is particularly significant.
Quantum dots are composed of a finite number of atoms, with dimensions on the order of nanometers in all three dimensions. Quantum dots are generally spherical or quasi-spherical, and are nanoparticles with a stable diameter of 2 to 20 nm made of semiconductor materials (usually composed of IIB~VIA or IIIA~VA elements). Quantum dots are collections of atoms and molecules on the nanometer scale, which can be composed of either one semiconductor material or two or more semiconductor materials. As a novel semiconductor nanomaterial, quantum dots have many unique nanoproperties.
Since the unique properties of quantum dots are based on their own quantum effects, when the particle size enters the nanoscale, size confinement will cause size effects, quantum confinement effects, macroscopic quantum tunneling effects and surface effects, thus deriving nanosystems with constant The low-dimensional physical properties of the macroscopic system and the microscopic system are different, showing many physical and chemical properties different from those of the macroscopic bulk material, and it has a very broad application prospect in nonlinear optics, magnetic media, catalysis, medicine and functional materials.
Compared with traditional dye molecules, quantum dots have many advantages such as rich color, continuous stability and special optical properties in life science applications. In terms of semiconductor devices, the low density of states and sharpening of energy levels in quantum dots lead to a three-dimensional quantum confinement effect on the carriers in the quantum dot structure, which changes its electrical and optical properties. Significant in-band transitions can occur under normal incidence. These properties make semiconductor quantum dots have extremely broad application prospects in single-electron devices, memory and various optoelectronic devices.
Recently, with the approval of the National Standardization Administration and the Chinese Academy of Sciences, the National Nanotechnology Standardization Technical Committee approved the establishment of a low-dimensional nanostructure and performance working group on the Taizhou Graphene Research and Testing Platform (under Giant Nano), numbered SAC/TC279/WG9. The low-dimensional nanostructure and performance working group is mainly responsible for and coordinating the national low-dimensional nanostructure and performance standardization work. Taizhou Graphene Research and Testing Platform Co., Ltd. is the responsible unit of the working group.
At the same time, Juna Group brings high-quality materials to customers around the world, such as aminated graphene quantum dots, carboxylated graphene quantum dots, carboxylated graphene quantum dot powder, chlorine-containing functionalized graphene quantum dots, green fluorescent graphite Graphene quantum dots, carboxylated graphene quantum dots, etc.
