外文摘要：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℃.The developed sensor exhibits a high-temperature sensitivity of 135 pm/℃.The proposed method has enormous potential for the development of fiber-end temperature sensors.
