  • Abstract
    Optical high-temperature sensing using the fluorescence intensity ratio (FIR) technique of green up-conversion emissions at 523 and 546 nm in Er3+-Y3+-codoped Al2O3 was studied in a wide temperature range of 295 K-973 K. The maximum sensitivity and the temperature resolution derived from the FIR technique are approximately 0.0035 K-1 and 0.3 K, respectively, which indicated that Er3+-Y3+-codoped Al2O3 plays an important role for applications in the optical high-temperature sensing.
