| 中文摘要 | a 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. |
