Optical Temperature Sensor Using Infrared-to-Visible-Frequency Upconversion in Er3+/Yb3+-Codoped Bi3TiNbO9 Ceramics

         

摘要

@@ An optical temperature sensor based on infrared-to-visible upconversion emission in Er3+/Yb3+ co-doped Bi3 TiNb O9(BTN) ceramics is reported.The fluorescence intensity ratio of the green upconversion photoluminescence(UC-PL) around 524nm and 545nm depends on temperature.The operating temperature range and the maximum sensitivity of Er3+/Yb3+ co-doped Bi3TiNbO9 ceramics are 123-693K and 0.0032K-1, respectively.BTN:Er3+/Yb3+ ceramic has good thermal, physical and chemical stability, great UC-PL intensity and low cost fabrication.The results imply that Er3+/Yb3+ co-doped Bi3TiNbO9 ceramic is promising for applications in wide-temperature-range sensors.
