Abstract

Gold nanoparticle embedded in Er³⁺-Tm³⁺-codoped tellurite-glass are able produce two effects on the emission properties these glasses: (i) quenching on direct-emission under excitation by a 405 nm laser diode, or (ii) enhancement on upconversion-emission under excitation by a 976 nm laser diode in these glasses. Both effects were investigated from the luminescence decay dynamics of ions. The localized surface plasmon resonance band of gold nanoparticles at around 580 nm resulted in the quenching/enhancement of Er³⁺-Tm³⁺ emission for the Er³⁺:(⁴S_3/2→⁴I_15/2) transition. These hybrid materials can be utilized for various photonic applications, e.g. infrared to visible light converters or emitting green light.
