Description
Cadmium Selenide (CdSe) Nanopowder / Nanoparticles (99.95%, <100 nm)
Cadmium Selenide (CdSe) Nanoparticles are a II–VI semiconductor nanomaterial with excellent optical, electronic, and photonic properties. With a purity of 99.95% and an average particle size of <100 nm, CdSe nanopowder is widely studied and applied in quantum dots, optoelectronics, photovoltaics, and photocatalysis.
CdSe exhibits a direct band gap (~1.74 eV at room temperature), making it highly efficient for light absorption and emission. This property makes CdSe nanoparticles particularly suitable for solar cells, LEDs, photodetectors, and biomedical imaging applications.
