A study on a new synthetic method of CdS and CdSe nanoparticles and their organic/inorganic nanocomposite

Materials such as CdS and CdSe inorganic nanoparticles have photoluminescence. Sodium oleate has been used as effective stabilizers for the synthesis of CdS and CdSe nanoparticles in water by autoclave method. Photoluminescence of CdS and CdSe with particle size of 5-14 nm showed lambda(max) at 520 nm and 600 nm, respectively, when were excited at 365 nm. These nanoparticles doped into the PVA resulted in the organic/inorganic films (PVA/CdS, CdSe). Photoluminescence, X-ray diffraction and transmission electron microscopy were employed for their characterization.
