Quantum dots/cadmium sulfide nanocrystals
Cadmium sulfide nanocrystals are single-crystal semiconductor nanoparticles that are well-known as quantum dots. The uniqueness of these quantum dots arises from the fact that their optical and electrical properties vary with particle size, and they offer flexible processing possibilities. The size of these quantum dots ranges from 2 to 7 nanometers, and they possess optical properties across the ultraviolet to blue wavelength spectrum. Typical cadmium sulfide quantum dots are inorganic semiconductors coated with organic ligands on their surface. These ligands enable the stability, solubility, and processability of these nanocrystals in solvents. Unlike organic dyes, quantum dots absorb a wide range of light and emit a limited spectrum of light. This property allows for the emission of true colors at specific wavelengths when excited by a broad range of light. The luminescent potential of quantum dots is determined by the quality and size distribution of the nanocrystals in the solvent.
