Carbon Dots in Hydroxy Fluorides: Achieving Multicolor Long-Wavelength Room-Temperature Phosphorescence and Excellent Stability via Crystal Confinement

Nano Letters, Journal Year: 2022, Volume and Issue: 22(13), P. 5127 - 5136

Published: June 14, 2022

Carbon dots (CDs) have aroused widespread interest in the construction of room-temperature phosphorescent (RTP) materials. However, it is a great challenge to obtain simultaneous multicolor long-wavelength RTP emission and excellent stability CD-based Herein, novel universal "CDs-in-YOHF" strategy proposed generate by confining various CDs Y(OH)xF3–x (YOHF) matrix. The mechanism triplet related space confinement, formation hydrogen bonds C–F bonds, electron-withdrawing fluorine atoms. Remarkably, lifetime orange-emissive CDs-o@YOHF longest among reported single-CD-matrix composites for above 570 nm. Furthermore, exhibited higher performance at long wavelength comparison CDs-o@matrix (matrix = PVA, PU, urea, silica). resulting CDs@YOHF shows photostability, thermostability, chemical stability, temporal which rather favorable information security, especially complex environment.
