Abstract
Tellurite based glasses of composition TeO2-WO3- Li2O-Yb2O3- Er2O3 with different Ag2O (TWLEYA) concentrations has been prepared by melt quenching technique. Heat-treatment process of glass samples was performed to nucleate Ag-NPs and glass-ceramic nature of samples is evidenced by XRD measurement. For glass stability of transition temperature and onset crystallization of this glass, the system has been studied by DSC. Surface plasmon-enhanced photoluminescence in the glasses are measured in the range 535-550 nm green and 640-650nm red under 488nm excitation. Raman spectrum revealed glasses were mainly formed by the [TeO4], {TeO3}, [WO4] and [WO6] units and [TeO4] units convert to [TeO3] units with the addition of WO3 and Li2O into tellurite glasses. The result indicates that enhancement of Raman intensity and a small shift has been grown due to surface plasmon of 12hrs heat-treated Ag nanoparticle doped TWLEYA glass. Thus enhanced optical response of the glass samples with Ag-NPs is attributed to the growth of the local field and vicinity of the nanoparticles on erbium ions. With optimum 0.7 mol%, Ag NPs in TWLEYA glass may be utilized for their potential applications in photonic devices
