Photoluminescence study of Sm~(3+) doped Zinc Lead Tungsten Tellurite glasses for reddish-orange photonic device applications

摘要

Zinc lead tungsten tellurite glasses with varying concentration of samarium ions were synthesised by melt quench method and studied their absorption, excitation, emission and decay spectral features to understand their utility in visible photonic devices. The bonding parameter evaluated from the absorption spectra reveals the nature of bonding between Sm
