Abstract

Blue luminescent reduced state carbon dots were prepared by reducing carbon dots with NaBH4. 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.
