Design and synthesis of narrow bandwidth emission triangular CQDs. a Synthesis route of the NBE-T-CQDs by solvothermal treatment of PG triangulogen. The typical aberration-corrected HAADF-STEM images of B- (b), G- (c), Y- (d), and R-NBE-T-CQDs (e), respectively. Scale bar, 2 nm. Photographs of the NBE-T-CQDs ethanol solution under daylight (f) and fluorescence images under UV light (excited at 365 nm) (g). The normalized UV-vis absorption (h) and PL (i) spectra of B-, G-, Y-, and R-NBE-T-CQDs, respectively
