Photoluminescence: Three Colors Emission from S,N Co‐doped Graphene Quantum Dots for Visible Light H2 Production and Bioimaging (Advanced Optical Materials 3/2015)

On page 360, Z. Sun and co-workers synthesize S,N-co-doped graphene quantum dots (S,N-GQDs) via a solvothermal route. The S,N-GQDs exhibit a strong absorption and near excitation-independent three-primary-color emission (blue, green, and red). These optical properties make S,N-GQDs possible for use as sensitizers for light absorption and as probes for bioimaging with visible light excitation.
