摘要：The significant temperature effects on up-conversion emissions of Nd3+:Er3+:Yb3+ co-doped borosilicate glass excited by a 978-nm semiconductor laser have been investigated and two-stage sensitization of Yb3+ -> Er3+ -> Nd3+ is discussed. The fluorescence intensity ratio of the near-infrared emission at 813 and 887 nm of Nd3+ ions takes on trustworthy repeatability in the temperature range of 296-670 K because of their strong photoluminescence intensities and the sample is more suitable for sensitive high-temperature sensor.
