Carbon quantum dots with honeycomb structure: a novel synthesis approach utilizing cigarette smoke precursors

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Jan. 23, 2024

Abstract This study presents a novel approach to synthesizing honeycomb carbon quantum dots (CQDs) from cigarette smoke by hydrothermal process. A comprehensive characterization of these CQDs, conducted through high-resolution transmission electron microscopy (HRTEM), showcases their unique structure, with an average particle size 6.3 nm. Photoluminescence (PL) in CQDs is captivating phenomenon where nanoscale structures emit strong blue luminescence at 461 nm upon exposure ultraviolet light, excitation peak occurring 380 Fourier Transform Infrared (FTIR) analysis also identifies specific functional groups within the offering valuable insights into mechanisms governing photoluminescence. Analysis spectra indicates presence both aromatic C=C bonds 254 and C–O 280 420
