| Description | Journal: Nanotechnology A one-step hydrothermal synthesis of nitrogen and silicon co-doped fluorescence carbon quantum dots (N,Si-CQDs) from citric acid monohydrate and silane coupling agent KH-792 with high product yield (PY) of 52.56% and high quantum yield (QY) of 97.32% was developed. This greatly improves both PY and QY of CQDs and provides a new approach for a large-scale production of high-quality CQDs. Furthermore, N,Si-CQDs were employed as phosphors without dispersants to fabricate white light-emitting diodes (WLEDs) with the color coordinates at (0.29, 0.32). It is suggested that N,Si-CQDs have great potential as promising fluorescent materials to be applied in WLEDs. |
