光学温度传感器能够准确地检测生物系统中的温度，对于医疗监测的发展至关重要。为了挑战现有技术，需要设计出具有多波长发射的单发光中心掺杂材料，以实现更多模式和更高分辨率的光学温度传感器。本文首次报道了一种具有明显热致变色现象的Er 3+单掺KYF 4纳米微晶玻璃陶瓷，基于热扰动模型，该玻璃陶瓷表现出不同的温度依赖的绿色、红色和近红外发光行为。此外，还将单掺Er 3+的GC光纤拉制成多模光纤温度传感器，具有上级的测温分辨率，
Optical temperature sensors, which can accurately detect temperature in biological systems, are crucial to the development of healthcare monitoring. To challenge the state-of-art technology, it is necessary to design single luminescence center doped materials with multi-wavelength emission for optical temperature sensors with more modes and higher resolution. Here, an Er3+ single-doped KYF4 nanocrystals glass ceramic with an obvious thermochromic phenomenon is reported for the first time, which shows a different temperature-dependent green, red, and near-infrared luminescence behavior based on thermal disturbance model. In addition, Er3+ single-doped GC fiber was drawn and fabricated into multi-mode optical fiber temperature sensor, which has superior measured temperature resolution (
