Ethylenediamine Assisted Synthesis of o‐Phenylenediamine‐Based Red Emissive Carbon Quantum Dots: A Strategy to Improve the Fluorescence Quantum Yield

Advanced Optical Materials, Год журнала: 2024, Номер unknown

Abstract O ‐phenylenediamine (OPD) is commonly used as a precursor in the preparation of red emissive carbon quantum dots (R‐CQDs) due to sp 2 hybridized structure. However, low fluorescence yield (QY) OPD‐based R‐CQDs limits its application. Although some efforts have been made, improvement QY still limited. In this paper, strategy proposed improve by introducing ethylenediamine (EDA), which plays key role nitrogen (N) dopant high N content. The molar ratio OPD EDA (M /M ), reaction time (t) and temperature (T), amount concentrated H SO 4 (V H2SO4 are optimized. with 32.65% full width at half maximum (FWHM) emission narrow 25 nm obtained via hydrothermal procedure under optimal experimental conditions (i.e., M = 1/3, t 6 h, T 180 °C V mL). Such higher than most reported R‐CQDs. Besides, it found that acts catalyst addition protonation. enhancement attributed increase aromatic N‐containing heterocyclic structures (C═N) after introduction catalysis .
