Abstract
Blue luminescent reduced state carbon dots were prepared by reducing carbon dots with NaBH(4). The quantum yield of the reduced state carbon dots increased from 2% to 24% and the maximum emission wavelength shifted from 520 to 450 nm. This offers a simple pathway to enhance the luminescence of carbon dots.
摘要
通过 NaBH(4)还原碳点制备了蓝色发光的还原态碳点。还原态碳点的量子产率从 2%增加到 24%，最大发射波长从 520nm 位移至 450nm。这为增强碳点的发光提供了一种简单的途径。
