. In our work, the temperature sensing properties and intrinsic mechanism based on a bismuth–erbium co-doped optical fiber (BEDF) were explored. Through temperature sensing experiments, we found that when the 980-nm pump laser was used, the fluorescence intensity ratio (FIR) at 1560 and 1435 nm showed a good linear relationship at different temperatures and its sensitivity reached 0.1151 dB/°C, the accuracy was 0.2°C, and the R2 of the FIR curve is about 0.9923. At the same time, we also proposed a detection algorithm to judge the working state of the sensor. By changing the BEDF coating material while the fiber is being fabricated, the temperature measurement range can be further improved. The optical fiber temperature sensor will have a broader range of applications.

“…[1][2][3] Traditional temperature sensors perform poorly in strong electric and magnetic field environments. In contrast, optical fiber sensors offer numerous advantages, including high precision, sensitivity, compact size, and robust electromagnetic interference resistance, and good high-voltage insulation performance, [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] making them a focal point of research in recent years.…”

To facilitate temperature detection in industrial production settings, an optical fiber temperature transmitter was developed utilizing fluorescence lifetime as its basis. Comprising an upper computer, fiber optic temperature transmitter, and optical fiber probe, the system incorporates a scalable fluorescence detection module. Real‐time temperature calculation is achieved through a microcontroller based on the fluorescence lifetime, with results transmitted to the upper computer, the optical fiber sensor exhibits a resolution of 0.01°C and an accuracy of ±0.3°C.
