Description
Summary:To achieve higher quality temperature measurement, this paper studies the rare-earth-doped Na2Ca3Si2O8 and BaZrSi3O9 matrix luminescent materials. The paper mainly adopts sol-gel method to prepare luminescent material in the form of thin film and powder. By comparing the thermodynamic reaction of the two materials and their respective properties, the differences between the two are further distinguished. The results illustrate the temperature-dependent up-conversion luminescence mechanism of thin film and explain the relationship between the up-conversion luminescence intensity and temperature. The results show that more accurate temperature measurements can be achieved.
