Synthesis and optical properties of CdS/PVA nanocomposites
چکیده انگلیسی
Yellow and orange light emission from nanoparticles of cadmium sulphide embedded in polyvinyl alcohol (PVA) has been observed as thin films. The synthesis of CdS embedded in PVA has been performed via two different routes at room temperature and the composite films have been prepared by vacuum evaporation of solvent on a glass surface. The absorption spectra show a blue shift of more than 80 nm as compared to bulk CdS band-gap. The photoluminescence studies indicate the air stable light emission from the films. Bright light emission at 515 nm (2.41 eV) has been observed without using PVA.
