| Abstract: | Yb3+:Er3+ co-doped oxy-fluoride ceramics glass has been prepared. The mechanism of up-conversion emissions about Er3+ was discussed, and the temperature properties of green up-conversion fluorescence between 303 and 823 K were investigated. The results show that the sensitivity of this sample reaches its maximum value, about 0.0047 K-1, when the temperature is 383 K, indicating that this kind of sample can be used as high temperature and high sensitivity optical temperature sensor. |
