We report on linear and nonlinear optical properties of chalcopyrite CuInS2 nanoparticles
prepared via thermal decomposition of metal complexes. A broad photoluminescence band
with a large Stokes shift is observable, and its decay time depends strongly on the emission
energies. The photoluminescence is ascribed to radiative recombination of photo-excited
carriers after multiple-step hopping among deep trapping sites on nanoparticle surfaces.
The imaginary part of the third-order susceptibility exhibits a resonant behaviour at the …
