Growth and spectroscopic characterization of CdSe nanoparticles synthesized from CdCl2 and Na2SeSO3 in aqueous gelatine solutions

CdSe nanoparticles were synthesized in comparatively mild conditions from Na2SeSO3 and CdCl2 in aqueous gelatine solutions. Kinetics of the formation and growth of CdSe nanocrystals as well as the effect of various parameters of reacting mixture on the size of CdSe nanocrystals are investigated. Optical properties of thin gelatine films, containing CdSe nanoparticles of different size, are characterized using absorption and Raman spectroscopy.
