Silver nanoparticles assisted spectral features enhancement of Samarium-Zinc-Tellurite glass

Achieving the enhanced optical properties of rare earth doped inorganic glasses by embedding metallic nanoparticles (NPs) is ever-demanding in photonics. Optimized doping of NPs and subsequent thorough characterizations for improved absorption and emission are the key issues for lasing glasses. We i...

Optimized doping of NPs and subsequent thorough characterizations for improved absorption and emission are the key issues for lasing glasses.
