Abstract:

This paper introduces a college comprehensive chemical experiment about the synthesis, characterization and luminescence measurement of long-persistent phosphors. The experiment covers various aspects, including the preparation of spinel structure alkaline earth aluminate phosphors, phase and luminescent properties characterization, and so on. The experimental process is not only safe, but also fast, simple, easy to operate, and visually appealing. By actively engaging in this experiment, students can gain a better understanding of the physical and chemical mechanisms involved in solution combustion reactions, as well as enhance their practical laboratory skills. Furthermore, it serves as a platform to showcase the beauty of chemistry, unravel the limitless allure of science, and ignite students' curiosity for scientific research.

Key words: Long persistent phosphors, Solution combustion method, Beauty of chemistry, College comprehensive chemical experiment
