Abstract
By the method of electrosynthesis with the simultaneous extraction in xylene obtained CdTe and ZnSe nanoparticles in the size of 2-3 nm by using of electrolytes based on (NH4OH, CdSO4 and Na2TeO3) and (H2SO4, H2SeO3, ZnSO4). The mechanism formation of nanoparticles consists of the electrochemical stage formation of telluride or selenide ions and of CdTe and ZnSe chemical stage formation determined by cyclic voltammetry. Spectral and photoluminescent studies have shown that of the obtained nanoparticles have an intensive absorption band of 350 to 450 nm with the presence of several double exciton band on the optical spectrum and the bright blue photoluminescence, the spectrum of which also has consist with two bands that’s corresponds to exciton and defective photoluminescence. From the obtained colloidal solutions, an optical nanocomposite was synthesized on the basis of a liquid crystalline matrix of cadmium caprylate (CdC8) with 0.5 mol% of CdTe and ZnSe nanoparticles.
