| In this paper, the basic principle of luminescence thermometry and the composition of typical systems are introduced, with discussion on the measurement errors and uncertainty evaluation models of luminescence thermometry. The importance of measurement error analysis and measurement uncertainty evaluation in the research and application of luminescence thermometer is pointed out. In the analysis of measurement errors, it is crucial to comprehensively consider the influence of internal device parameters and the measurement environment on luminescence thermometry parameters, such as luminescence lifetime and intensity ratio. It can significantly minimize systematic errors and enhance the accuracy of temperature measurement to optimize the excitation light source, phosphors, detectors, data acquisition, and data processing schemes, along with to conduct thorough environmental factor analysis and calibration. Furthermore, to investigate the physical mechanisms that cause variations in the emission characteristics of phosphor due to factors other than temperature can lay a theoretical foundation for developing more adaptable luminescence thermometry materials. In the evaluation of measurement uncertainty, the uncertainty in temperature measurement based on luminescence lifetime and intensity ratio can be described using mathematical models. This quantified temperature measurement uncertainty serves as a basis for guiding the optimization and application of high?precision luminescence thermometry systems. |
