Synthesis, characterization and non-linear optical response of organophilic carbon dots
Original language description
For the first time ever we report the nonlinear optical (NLO) properties of carbon dots (C-dots). The C-dots for these experiments were synthesized by mild pyrolysis of lauryl gallate. The resulting C-dots bear lauryl chains and, hence, are highly dispersible in polar organic solvents, like chloroform. Dispersions in CHCl3 show significant NLO response. Specifically, the C-dots show negative nonlinear absorption coefficient and negative nonlinear refraction. Using suspensions with different concentrations these parameters are quantified and compared to those of fullerene a well-known carbon molecule with proven NLO response. Carbon dots (C-dots) are a new and intriguing class of luminescent nanoparticles with properties complementary to the traditionalmetal-containing quantum dots [1]. The combination of multicolor and tunable emission, controlled surface chemistry, low toxicity, and solvent dispersability in one simple platform have made C-dots attractive for a range of optical, sens
