Carbon Dots: Zero-Dimensional Carbon Allotrope with Unique Photoinduced Redox Characteristics
Weixiong Liang, Christopher E. Bunker, Ya‐Ping Sun
Abstract
Carbon dots (CDots) exploit and enhance the intrinsic properties of small carbon nanoparticles. Their optical absorptions and photoinduced redox characteristics are competitive with those of conventional semiconductor quantum dots at one end and fullerenes and other carbon nanomaterials at the other. Highlighted in this mini review are the effective photon harvesting over a broad spectral range by CDots and their subsequent excited-state charge transfer processes and interactions, which have enabled their use as sensors, for photodynamic effects, and in various energy conversion technologies.
