Photoluminescent nanomaterials continue to garner research attention becauseof their many applications. For many years, researchers have focused on quantum dots (QDs) of semiconductor nanocrystals for their excellent performance and predictable fluorescence color variations that depend on the sizes of the nanocrystals. Even with these advantages, QDs can present some major limitations, such as the use of heavy metals in the high-performance semiconductor QDs. Therefore, researchers continue to be interested in developing new QDs or related nanomaterials. Recently, various nanoscale configurations of carbon have emerged as potential new platforms in the development of brightly photoluminescent materials.

As a perfect π-conjugated single sheet, graphene lacks electronic bandgaps andis not photoluminescent. Therefore, researchers have created energy bandgaps within graphene as a strategy to …
