C
arbon quantum dots (CQDs) are potential candidates for
numerous modern nanotechnologies and biomedical
research. Owing to their simple one-pot synthesis, unique
excitation-dependent emission, excellent photochemical
stability, and high biocompatibility, these water miscible
CQDs have shown great potential as an alternative source
to conventional organic fluorescent dyes and inorganic
semiconductor QDs. Considering these advantages of CQDs, we
have synthesized fluorescent CQDs fromvarious natural sources
such as pomegranate extract, D-glucose and beetroot aqueous
extract in a very simple, green and cost-effective way for white
light emitting material, chemical sensing and biomedical
applications. The details of the synthesis, photophysical
properties and applications of these CQDs are also studied.
