Photoluminescence study of Sm3+-Yb3+ co-doped tellurite glass embedding silver nanoparticles
We report on the upconversion emission of Sm3+ ions doped tellurite glass in the presence of Yb3+ ions and silver nanoparticles. The enhancement of infrared-to-visible upconversion emissions is achieved under 980 nm excitation wavelength and attributed to the high absorption cross section of Yb3+ io...
