Investigation on Process Time to Fabricate Carbon Dot-based Electroluminescent Devices

Abstract

In this work, a study about how to produce color conversion layer for Light Emitting Diodes (LEDs) in a simple, fast and cost-effective way, using carbon dots (CDs) made from urea (U) and citric acid (CA), is reported. In our method, an auto generated matrix of urea and other subproducts such as cyanuric acid, incorporates the CDs, drastically reducing their intrinsic photoluminescence self-quenching in solid state form.
