The glasses of composition TeO 2 -WO 3 -Li 2 O-Er 2 O 3 with AgNO 3 (TWLEOAG) were prepared by the high-temperature melting method. Surface Plasmon resonance (SPR) bands are observed in the range 520-535 nm and 640-650nm of without erbium-doped glass by absorption spectrum. The TEM measurement reveals the presence of spherical AgNPs in this glass. The DSC has also been analyzed for the stability of transition temperature T g and on set crystallization T 0 of this glass system. The Raman spectrum revealed that TWLEOAG glasses were mainly formed by the [TeO4], {TeO3}, [WO 4 ] and [WO 6 ] units and [TeO 4 ] units convert to [TeO 3 ] units with the addition of WO 3 and Li 2 O content into tellurite glasses system. In particular TWLEOAG05 glass samples, heat-treated different time interval system reveal the enhancement in Raman peaks intensity with small shift in due to Ag nanoparticle. Also photoluminescence enhancement of red upconversion compare to green emission of TWLEOAG05 for different annealing duration has been observed under 808nm excitation. In this work optimum 0.5 mol% AgNP in TWEOAG glass would be useful for optical devices.
