Carbon nanoparticles upon simple surface passivation exhibit bright photoluminescence.
Reported here is a new finding that these carbon dots are also strongly two-photon …

It was found and recently reported that small carbon nanoparticles can be surface-
passivated by organic or biomolecules to become strongly fluorescent. These fluorescent …

We report on the two-photon excited fluorescence of conjugated polymer dots (CPdots). As a
new class of two-photon fluorescent probes, CPdots exhibit two-photon action cross sections …

We report that nanoscale carbon particles (carbon dots) upon simple surface passivation are
strongly photoluminescent in both solution and the solid state. The luminescence emission …

Carbon dots have been gaining attention in the field of nanobiotechnology due to their
