Progress of rare earth europium complexes in the field of temperature luminescence sensing

Abstract

Rare earth luminescent complex materials, its unique 4f-4f electronic transition, which shows excellent luminous performance, especially the europium complex materials, with temperature dependent luminescent performance of europium complex can achieve high sensitivity, high efficiency of temperature sensing process, can be applied to environmental engineering, energy technology and other fields of temperature measurement and monitoring. This review introduces the research progress of europium complex in temperature luminescence sensing system, summarizes the complex material category and analyzes the influencing factors of temperature response sensitivity, further summarizes the vibration relaxation and energy transfer, and introduces the preparation of europium EVA composite complex and research results in crystal silicon solar cells, for the study of lanthanide metal complexes temperature sensing performance, in order to open the door to the practical application of such materials.
