Abstract

Photoluminescent carbon dots (CDs) are synthesized and derived from carboxyl-modified PAMAM dendrimer precursor by a one-pot solvothermal method. The obtained CDs exhibit highly bright Yellow-emitting fluorescence with quantum yield of 62.6%. In practice, using their excellent photoluminescence and good compatibility, the CDs are processed with polymers for various fluorescent nanocomposites (such as film, microfiber and bulk hydrogel) and applied as light conversion materials for white LEDs.
