AbstractA facile route to assemble cadmium sulfide (CdS) quantum dots (QDs) uniformly on the surface of titanate nanobelts (TNBs) through electrostatic interactions is demonstrated. The photophysical properties of the resulting TNB-CdS nanostructured composite, including optical limiting properties, were studied using ultraviolet-visible absorption spectroscopy, photoluminescence spectroscopy, and the open aperture Z-scan technique in the nanosecond regime using a laser with a wavelength of 532 nm. The linear and nonlinear optical properties of this composite nanostructure were strongly influenced by a possible charge/energy transfer process between the QDs and TNBs. The as-prepared TNB-CdS composite offers an optical limiting effect that is superior to that of unmodified CdS QDs and TNBs. The main contributors to the enhanced optical limiting effect in the TNB-CdS composite were a combination of nonlinear scattering and increased nonlinear absorption resulting from efficient charge/energy transfer at the CdS/TNB interface.
