制备了Er3+ Yb3+ 共掺微米级高折射率TiBa玻璃颗粒和微球 ,玻璃基材主要成分为TiO2 BaCO3 Ba(NO3) 2 CaCO3 SiO2 等 ,掺入 1mol%Er2 O3+3mol%Yb2 O3.用 976nm激光激发测量了它们的上转换绿光发射 ,发现当抽运功率大于 30mW(功率密度约为 10 0 0W·cm- 2 )时 ,5 2 4nm峰的强度大于 5 4 7nm峰的强度 ,随功率的增大 ,其强度差越来越大 ,实验判断 ,这是由于材料吸收抽运光而升温所致 Er3 + Yb3 + co-doped micron-grade high refractive index TiBa glass particles and microspheres were prepared. The main components of the glass substrate were doped with 1 mol% Er2O3 + 3 mol% Yb2O3 and doped with 976 nm laser Excitation measured their upconversion green emission and found that when the pumping power is greater than 30 mW (power density is about 100 W · cm -2), the peak intensity at 524 nm is greater than the intensity at 547 nm peak, Increase, the intensity difference is bigger and bigger, the experimental judgment, this is because the material absorbs the pump light to cause the temperature to rise
