In order to integrate the synthesis and characterization process of luminescent materials into experimental teaching,and to solve the problems of expensive instrument,high experimental costs,and the risk of high-temperature during the experimental process,a virtual simulation experi-mental teaching system for solid-state synthesis of upconversion phosphor and spectral measurement was constructed.Based on the principle of"high order,innovation and challenge",a virtual simula-tion experiment teaching content had been designed,and a teaching evaluation model that separates"learning"and"examination"had been established.Through virtual training on experimental tech-niques,equipment cognition,light path disassembly and measurement,the aim was to enable for students to fully understand and master the physical process of upconversion luminescence,the process of solid-state method for preparing upconversion phosphor,the use of related instruments,and the measurement and analysis methods of emission spectra.This virtual simulation experiment provided a new way for promotion of scientific research to teaching,and expanded the breadth and depth of basic physics experiment teaching.
