Abstract

We report the development of a point temperature sensor, based on monitoring upconversion emission from erbium:ytterbium-doped tellurite coatings on the tips of optical fibres. The dip coating technique allows multiple sensors to be fabricated simultaneously, while confining the temperature-sensitive region to a localised region on the end-face of the fibre. The strong response of the rare earth ions to changing temperature allows a resolution of 0.1-0.3 °C to be recorded over the biologically relevant range of temperatures from 23-39 °C.

摘要

我们报告了一种点温度传感器的研发情况，该传感器基于监测光纤尖端掺铒镱碲酸盐涂层的上转换发光。浸涂技术可同时制造多个传感器，同时将温度敏感区域限制在光纤端面的局部区域。稀土离子对温度变化的强烈响应使得在23至39°C的生物相关温度范围内能够记录到0.1 - 0.3°C的分辨率。
