Revealing the in-situ growth mechanism of carbon dots confined in ZIF-8 as multicolor fluorescent material with high photothermal stability.

Carbon dots (CDs) based fluorescent materials offer tremendous potential for application in high-definition displays and advanced illumination systems. However, achieving solid-state CDs-based phosphors with robust photothermal stability remains a critical challenge. In this study, multicolor CDs@ZIF-8 phosphors were synthesized by precisely controlling the carbonation degree of CDs under the confinement effect of ZIF-8.
