Long Life–time Room–temperature Phosphorescence of Carbon Dots in Aluminum Sulfate
View through CrossRef
Abstract
Herein we report the observation of room‐temperature phosphorescence from carbon dots (CDs) embedded in aluminium sulfate. Phosphorescence emission in CDs was achieved by incorporating C=O/C=N functionalities on the carbon dots (CDs) in a single‐step reaction. Benzene‐1, 3, 5‐tricarboxylic acid and formamide were used as precursors, and the resulting CDs in aqueous dispersion show excellent fluorescence in the blue region with quantum yield about 42.7%. On embedding CDs in aluminum sulfate, a green after‐glow, with phosphorescence life‐time of ∼876 ms was observed. The 1931 CIE color parameters corresponding to the phosphorescence emission (0.26, 0.36) indicated that the emission is in the white‐gamut region of the chromaticity diagram.
