摘要：

Temperature is a common and significant physical quantity, particularly under harsh conditions such as a high voltage or strong electric/magnetic fields. In this study, we developed an all- fiber- optic temperature sensor based on a fiber- end microstructure doped with quantum dots (QDs). The microstructure was fabricated on a fiber tip using two- photon polymerization technology. The results show that the fluorescence intensity of the QD microstructure is reduced with an increase in temperature, and the peak position of photoluminescence exhibits a linear change in the temperature range of 26-70 degrees C. The developed sensor exhibits a high- temperature sensitivity of 135 pm/degrees C. The proposed method has enormous potential for the development of fiber- end temperature sensors.
