Review outlines four distinct photoluminescence mechanisms in fluorescent carbon dots, indicating key pathways for engineered nanomaterial synthesis.

Key Points

To review and classify the fundamental photoluminescence mechanisms governing diverse fluorescent carbon dots to inform synthetic approaches and novel optical applications.
Synthesized existing literature evaluating the structural categories, chemical and physical properties, and synthesis routes for graphene quantum dots, carbon nanodots, and polymer dots.
Identified four distinct photoluminescence mechanisms: quantum confinement or conjugated π-domains governed by the carbon core, surface states arising from backbone and functional group hybridization, molecular states from embedded fluorophores, and crosslink-enhanced emission effects.
Categorized structural and optical dependencies showing that core structures, surface chemistries, and crosslinked networks differentially regulate emission behaviors across dot variants.
