摘要：荧光材料的发光强度受温度影响,使荧光测温能以较高空间和时间分辨率进行非接触式温度探测。为了实现器件微区的温度场表征,制备四种不同配合物的含铕荧光材料及聚合物薄膜Eu(DBM)3Phen/PS。研究表明,Eu(DBM)3Phen/PS薄膜不仅具有高温度灵敏度,而且荧光强度与温度呈高线性相关性,是性能较好的温敏漆。使用该铕配合物的薄膜和微区显微光谱系统,实现了微米级高空间分辨率的温度场测量,清晰识别电阻丝焦耳热引起的温度升高,证明了该荧光测温方法的有效性和实用性。利用该荧光探针有望进一步应用于微纳器件和材料微观机制的研究。
Fluorescence materials exhibit temperature-dependent luminescence intensity,enabling non-contact temperature detection with high spatial and temporal resolution.In order to characterize the temperature field in the micro-regions of the device,this study prepared four different complexes of europium-containing fluorescent materials and polymer films.The research demonstrates that the Eu(DBM)3Phen/PS film not only exhibits high temperature sensitivity but also shows a strong linear correlation between fluorescence intensity and temperature,making it a promising thermosensitive paint with superior performance.By utilizing films of this europium complex and a microscopic measurement system,temperature field measurements with micrometer-level spatial resolution were achieved,enabling clear identification of temperature increases induced by Joule heating of the resistance wire.This confirms the effectiveness and practicality of the fluorescence temperature measurement method.The utilization of this fluorescence probe holds promise for further applications in the study of micro-nano devices and materials’microscopic mechanisms.
