Résumé

Temperature-dependent multicolor luminescent materials are widely used in optical temperature sensing and related applications. However, most of these materials derive their luminescence from the radiation transition of rare earth (RE) ions. Therefore, the development of RE-free luminescent materials is of great significance for RE resources and environmental protection. Here, we propose a novel RE-free multicolor luminescent glass-ceramic (GC) and offer a color regulation strategy for defect-induced luminescence. As the temperature rises, thermal expansion alters the state of the defects, causing the emission color to gradually shift from cyan-green to dark blue. This color shift is reversible, returning to the original color as the temperature decreases. Moreover, the GC retains 97.2 % of its luminescence intensity after being submerged in water for one year, highlighting its excellent physicochemical stability. A pattern label prepared by this GC, exhibits excellent luminescent color-temperature response, indicating its potential application in high-temperature information indication.
