Cadmium Selenide Nanoparticles
Cadmium selenide nanoparticles are a type of semiconductor nanocrystals composed of cadmium and selenium atoms. They have unique optical and electronic properties due to their small size, which ranges from 1 to 10 nanometers in diameter.
Cadmium selenide nanoparticles can be synthesized through various methods, including colloidal synthesis, hot-injection synthesis, and microwave-assisted synthesis. These methods involve the reduction of cadmium and selenium precursors in the presence of stabilizing agents and solvents.
The properties of cadmium selenide nanoparticles can be tuned by controlling their size, shape, and composition. They exhibit size-dependent optical properties, such as quantum confinement and size-dependent bandgap, which make them useful for a variety of applications, including optoelectronic devices, solar cells, biomedical imaging, and sensing.
However, cadmium selenide nanoparticles also pose potential risks to human health and the environment due to their toxicity. Therefore, it is important to handle them with care and dispose of them properly to minimize their impact.
