摘要: Optical temperature sensing using upconversion fluorescence emission in Er3+/Yb3+-codoped Ga2S3:La2O3 chalcogenide glass excited at 1.06 μm is reported. Temperature measurements the region of 20–225 °C with a resolution approximately 0.5 °C excitation powers few tens milliwatts were obtained. The mechanism independent variations intensity, possible fluctuations transmission, and utilizes simple signal detection processing system. results also revealed that host material plays an important role performance
