Characterization and third-order optical nonlinearities of uniform surface-modified CdS nanoparticles.
Size-controlled uniform surface-capped CdS nanoparticles were readily prepared by an improved inverse microemulsion technique using hexanethiol as co-surfactant. The third-order optical nonlinearities were studied for the first time by newly-developed Z-scan technique, from which the enhanced nonlinear optical responses were observed after heat-treatment.
