Description
Summary:•The review summaries the types, mechanisms and applications of color-tunable organic room temperature phosphorescent materials.•The review compares the advantages and disadvantages of each type of material, and summarizes the similarities and differences of each mechanism of color-tunable organic room temperature phosphorescent materials.•The review provides suggestions for future development of color-tunable organic room temperature phosphorescent materials. Organic color-tunable phosphorescent materials depend upon multiple emission centers to achieve color-tunable phosphorescence with changes in excitation wavelength, temperature, time, and other external factors. Organic color-tunable phosphorescent materials are becoming increasingly popular due to their potential applications in anticounterfeiting, encryption and sensing. This brief review focuses on the formation of multiple emission centers in organic color-tunable phosphorescent materials and how to ensure that these multiple emission centers can simultaneously emit. In the future, materials with a large color tunable ranges, increased efficiency, and relatively long lives will be developed. [Display omitted]
