Summary:Optical high-temperature sensing using the fluorescence intensity ratio (FIR) technique of green up- conversion emissions at 523 and 546 nm in Er@@u3+@-Y@@u3+@-codoped Al@@d2@O@@d3@ 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@@u-1@ and 0.3 K, respectively, which indicated that Er@@u3+@- Y@@u3+@-codoped Al@@d2@O@@d3@ plays an important role for applications in the optical high-temperature sensing.
