Abstract

We have developed a scanning thermal probe microscope that operates in liquid environments. The thermal sensor is a fluorescent particle glued at the end of a sharp tungsten tip. Since light emission is a strongly thermally sensitive effect, the measurement of the particle fluorescence variations allows the determination of the temperature. No electrical wiring of the probe is needed. As a demonstrative example, we have measured the temperature map of a Joule-heated microheater immersed in a water∕glycerol solution. Both topographical and thermal images are obtained with a good sensitivity.

摘要

我们开发了一种可在液体环境中运行的扫描热探针显微镜。热传感器是一个粘贴在尖锐钨尖末端的荧光粒子。由于发光是一种对热非常敏感的效应，通过测量粒子荧光变化可以确定温度。该探针无需电气布线。作为一个示例，我们测量了浸没在水/甘油溶液中的焦耳加热微加热器的温度分布图。同时以良好的灵敏度获得了形貌图像和热图像。
