The characteristics of 1.53μm emissi on for the Er³⁺ doped bismuthate glasses containing Au nanoparticles (NPs) were studied under 980nm excitation.The absorption spectra show typical s urface plasmon resonance (SPR) peak of Au NPs appearing from 565ns to 586nm.Transmission electron micro scopic (TEM) image reveals densely inhabited Au NPs with different shapes and the size from 5nm to 16nm.The exper imental results indicate that 1.53μm emission intensity obviously enhances with the addition of AuCl,and reaches a ma ximum value in the glass containing 0.2wt% AuCl,which is 4.3times higher than that of glass without Au NPs,and then th e emission intensity decreases with the further increase of AuCl concentration.The enhancement of 1.53μm emission is a ttributed to the enhanced local field induced by Au SPR and energy transfer from Au^0to Er³⁺,while emission qu enching results from the energy transfer from Er³⁺ to Au⁰.
