Abstract

Abstract In this paper we report a rapid, low cost and easy way to produce solid-state luminescent carbon-dots (CDs) as color converters for light-emitting diodes (LEDs). CD precursor (urea and citric acid) molar ratio in aqueous solution is varied with the aim to find out the best conditions for an efficient color conversion and reducing photoluminescence quenching without any additional treatments, and to produce color conversion LEDs in a simple and green way.
