Abstract

Enhanced red fluorescence emissions of Pr3+ were observed in heavy metal germanium tellurite (HGT) glasses containing silver nanoparticles (NPs). The well-dispersed Ag NPs with a diameter ∼7 nm were evidenced by transmission electron microscope (TEM). With the introduction of Ag NPs, multichannel transition emission intensity of Pr3+ increased by ∼25% in comparison with that in the case without silver doping, which is attributed to the existence of the localized surface plasmon resonance (LSPR) referring to the characteristic absorption peaks. The larger the net emission power, the higher was the net emission photon number and the higher quantum yield in Pr3+ doped HGT glasses containing Ag NPs, presenting the effectiveness of utilizing laser. An efficient fluorescence emission and macroscopical sensitization illustrate that the Pr3+-doped HGT glasses with Ag NPs are potential materials, which improve the color-rendering index for laser illumination.
