A series of Er3+: Ag-bismuth glass nanocomposites were prepared by the conventional melt-quench method. The effect of nano-silver addition on the emission intensity of Er3+ was investigated. The experimental results indicate that, Ag nanoparticles of concentration of 0.2 wt% drastically enhances the intensity (∼4.6 folds) of 1.53 μm emission bands of Er3+. Local field enhancement induced by Ag0 surface...
The glass forming region of Bi2O3-B2O3-BaO ternary system was investigated. A serial of glass samples with high Bi2O3 content in Bi2O3-B2O3-BaO system were prepared by using conventional melting and quenching meld, and the refractive indexes and absorption spectra of samples were measured. It is found that the refractive index of samples as well as the UV absorption increase with the increase of BaO...
