Abstract

Highlights: Co-precipitation synthesis of Cr:CdSe nanoparticles. Zinc blende structure. Dopant dependent decrease in lattice parameters. CdSe related modes of vibration. Abstract: Chromium doped cadmium selenide (CdSe) nanoparticles were prepared via Chemical Co-precipitation Method. The effects of doping and doping concentration on structural and optical properties of the materials were studied. The structural characterization of samples carried out by using X-ray diffraction (XRD) indicated the formation of CdSe nanoparticles of zinc blend (cubic) polytype. It was also noted that lattice parameter decreases with increase in doping concentration. Fourier Transform Infrared Spectroscopy (FTIR) analysis of the samples shows the presence of several modes of vibration related to CdSe nanoparticles and the dopant.
