摘要 yb^3+:Er^3+ co-doped oxy-fluoride ceramics glass has been prepared. The mechanism of up-conversion emissions about Er^3+ 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. yb^3+:Er^3+ co-doped oxy-fluoride ceramics glass has been prepared.
