Three-color upconversion luminescence of rare earth codoped oxyhalide tellurite glasses徐时清,王玮,邓德刚,赵士龙,王焕平,鞠海东摘 要:<正>The red, green, and blue upconversion properties of Er3+/Tm3+/Yb3+-codoped oxyhalide tellurite glasses were studied under 980 nm LD excitation. The intense red (657 nm), green (530 and 545 nm), and blue (476 nm) emissions were......
, photoluminescence, and upconversion luminescence were measured on as-prepared glass and glass-ceramics. Luminescence spectra in the TGC samples revealed well-resolved, sharp stark-splitting peaks, which indicates... amplifier (EDFA). Upconversion luminescence was measured using 800 nm near-infrared light excitation. Drastically increased upconversion luminescence was observed from the TGC as compared to that from......
