Abstract
The structural and optical properties of Eu3+/CdSe nanocrystal in silica galss are presented. The presence of CdSe nanocrystals was confirmed using elctron diffraction studies. The nanocrystal size was determined from TEM micrographs. The phonon sideband spectrum (PSB) associated with the excitation transition 7F0–5D2 is used to determine the electron–phonon coupling constant and non-radiative de-excitation rate of the rare earth ions. The SiOSi vibrational energy obtained from the PSB spectrum is found to correlate with the FT-IR spectrum.
