Effect of Doping on Nano Cadmium-Selenide (CdSe) - Assessment Through UV-VIS Spectroscopy

Cadmium Selenide (CdSe) has been synthesized in nanocrystalline form by wet chemical synthesis and then CdSe/Polythiophene nanocomposite has been prepared. The characteristics of nanocrystalline CdSe and nanocomposite CdSe/Polythiophene has been studied by UV-VIS (Ultraviolet-Visible) Spectroscopy. Reduction in band gap energy is observed on addition of polymer polythiophene with CdSe nanocrystal.
