Dy3+掺杂Y-Al-O体系荧光材料的光学测温性能研究
Study on Dy3+Phosphors Doped Y-Al-O System Optical Temperature Measuring Performance
摘要
Abstract
Thermo-sensitive fluorescent materials show excellent potential for temperature sensing due to their non-invasive/semi-invasive optical properties and excellent anti-interference performance.Among them,Dy3+doped Y-Al-O system fluorescent materials have attracted much attention due to their excellent luminous efficiency and suitable thermal coupling energy levels.In this paper,Dy3+doped Y-Al-O system phosphor was synthesized by the high-temperature solid phase method,and the phase composition of the material was characterized by X-ray diffraction technology.The excitation and emission spectra were systematically measured by fluorescence spectrophotometer,and the temperature-sensitive characteristics of the material were analyzed.The results show that increasing the sintering temperature can promote the formation of the Y3Al5O12(YAG)phase and enhance the luminescence efficiency and temperature measurement performance of the material.The content of YAG phase in the phosphor synthesized at 1 600℃is as high as 97.8%.The maximum absolute sensitivity and the maximum relative sensitivity in the test temperature range of 100～1 300℃are 1.7×10⁻3℃⁻¹ and 3.8×10⁻3%℃⁻¹,respectively.Compared with the thermocouple measurement results,the maximum relative measurement error is only 0.5%.These studies highlight the potential value of Dy3+doped Y-Al-O system phosphors for temperature monitoring in a variety of industrial and scientific applications.关键词
