Summary/Abstract: Colloidal solutions of ~2 nm CdSe nanoparticles have been obtained by electrosynthesis with simultaneous extraction into p-xylene. The effect of electrolyte composition on the structure of electrodeposited CdSe nanoparticles has been established, their absorption and photoluminescence spectra have been analyzed. Exciton absorption of light by synthesized CdSe nanoparticles splits into three bands, which is characteristically for the small CdSe nanoparticles. Photoluminescence excited at wavelengths corresponding to curve bending decreases in intensity within the 350 -550 nm region with a maximum of 430 nm. This fact indicates on the formation of small (~ 2 nm) of CdSe nanoparticles in the process of electrosynthesis as well. Studies have shown that by the proposed method of electrochemical synthesis it is possible to obtain nanoparticles that are promising for the creation of optical liquid–crystalline composites.
