dc.description.abstract | The wavelength and irradiance dependence of excitonic nonlinear absorption in cadmium sulfide (CdS) nanocrystals (NC) were investigated. The dependence was analyzed by using Z-scan method with nanosecond laser pulses. The intrinsic excitonic nonlinear absorption was described using a two-level model. It was observed that the nonlinear absorption was increased when the particle size was less than the bulk Bohr diameter due to the quantum confinement effect. A third-order excitonic bleaching at low irradiance and fifth-order excitonic nonlinear absorption at higher irradiance were observed for both 3.0-nm-sized and 2.3-nm-sized CdS NCs. | |
