Abstract: A stable CdSe nanoparticle hydrosol was prepared upon addition of mercaptoacetic acid as a stabilizer. A nanocomposite was formed based on electrostatic interactions by poly (4-vinylpyridine) quaternary ammonium with CdSe nanoparticle. The formation of nanocomposite was confirmed and characterized by infrared spectrum (IR), inductively coupled plasma atomic emission spectroscopy (ICP-AES), transmission electron microscopy (TEM),UV-Vis spectrophotomery (UV-Vis), photoluminescence (PL) spectrophotometry, etc.The dispersive property and luminescence intensity of CdSe nanocrystals were improved and increased by the formation of the composite.

Key words: Nanocomposite, CdSe, Poly(4-vinylpyridine) quaternary ammonium,  Photoluminescence(PL), Energy transfer
