Comparative Study of Optical and Electrical Properties of CdSerSm and CdSe: Nd Nanocrystalline Thin Film

摘要

Rare earth (Sm or Nd) doped CdSe nanocrystalline thin film were grown onto the glass substrate by chemical bath deposition (CBD) method. Crystal structure were determined by XRD. The emission spectra of photoluminescence (PL) for Sm or Nd doped CdSe nanocrystalline thin film lies at 601nm. The band edge luminescence is responsible for PL. CdSe:Sm (6 ml, 0.01 M) and CdSe:Nd (4 ml, 0.01 M) give the highest PL intensity.
