Impact of annealing time on the optical response of zinc-boro-tellurite glass

Annealing time dependent optical properties of melt-quench synthesized Er3+-doped (0.5 mol%) zinc-boro-tellurite (ZBT) glasses containing silver (Ag) nanoparticles (NPs) (1.0 mol%) are reported. Heat treatment (HT) durations are varied to control NPs growth. Reduction of NPs sizes from 12.7 to 6.6 n...
