摘要
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-V is 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.
