Effect of heat treatment on green luminescence broadening of Er-doped ZnO-PbO tellurite glass ceramics
- Conference date: 3–7 December 2012
- Location: Indian Institute of Technology, Bombay, Mumbai, India
Er doped ZnO-PbO tellurite glass ceramics were investigated using Raman and photoluminescence. crystals dominate the Raman spectra for low PbO content, but another phase, attributed to is observed when the PbO content is increased. Photoluminescence broadening and intensity changes were observed in crystallized samples and attributed to the variation of local crystal environment around the erbium ions. The result confirms that the crucial erbium emission broadening and intensity variation is mainly due to in crystals.
