Graphitic Dots Combining Photophysical Characteristics of Organic Molecular Fluorophores and Inorganic Quantum Dots
journal contribution

properties, both organic molecular
fluorophores (MFs) and inorganic quantum dots (QDs) are extensively
used for bioimaging applications. However, limitations such as photobleaching
for the former or blinking, size, and toxicity for the latter still
constitute a challenge for numerous applications. We report here that
embedding MFs in graphitic carbon dots (GDs) results in fluorophores
which entirely tackle this challenge. Characterized by ultranarrow,
bright, and excitation-independent emission devoid of blinking and
photobleaching, these hybrid-featured nanoparticles also demonstrate
their unique photophysical performances at the single-nanoparticle
scale, making them appealing candidates for bioimaging applications.
