Due to their lower toxicity than cadmium-based semiconductor quantum dots, graphene quantum dots (GQDs) are attractive luminous materials for numerous light-emitting, biological, and energy applications. The luminous properties of GQDs drive their practical applications sand uses.
As a result, controlling and tailoring the emission properties of these materials to suit the specified optoelectronic applications is crucial. The researchers explored the fundamental properties, production methods, and strategies for incorporating GQDs into optoelectronic devices.
The scientists have created the principles of GQD luminescence, including reflections on defect-related features (i.e., oxygen functional groups and odd-numbered carbon rings in the basal plane). They propose new manufacturing criteria for graphene quantum dots with the goal of boosting luminescence efficiency. They’ve also proposed architectural designs for incorporating GQDs into optoelectronic devices based on the essential features’ architectural design.
