Abstract
Disclosed herein are materials and a micro-LED display with carbon-based light-emitting materials, carbon quantum dots, that are made by a solvothermal synthesis of a mixture of aromatic amino acid, 3,4-dihydroxy-L-phenylalanine (LDOPA), and urea in dimethylformamide (DMF). The mixture is heated in a sealed pressure reactor at a temperature, ranging from 120 degrees Celsius to 350 degrees Celsius, for 4-24 hours. The product is then purified to collect the solid powder. The purified CDs can be dissolved in an acrylate monomer solution or a polymer solution for material delivery and curing process on a target substrate for the applications, including light-emitting devices or sensors.
