Confinement Microenvironment Regulation of Carbon Dots in Zeolite for Multi‐Mode Time‐Dependent Phosphorescence Color Evolution

to produce an ultrafast-decaying red phosphorescence, with the intensity of the red component increasing as the temperature rises. The interplay of these luminescent centers with distinct decay rates activates fascinating multi-mode TDPC behavior as the temperature changes, resulting in dynamic afterglow evolutions from red to green at 298 K, orange to green at 273 K, and green to cyan to blue at 77 K. Leveraging the diverse luminescence of CDs@MnAPO-5, a multi-dimensional dynamic afterglow color pattern was developed for advanced anti-counterfeiting applications.
