摘要：

We investigated the optical properties of Zn nanocomposites with the lamellar structure of sodium dodecyl sulfate (SDS) molecules prepared by laser ablation in an SDS aqueous solution. The absorption band of the nanocomposites was found at the same wavelength as that of ZnO (370 nm). The peak positions of the nanocomposites in the photoluminescence and excitation spectra were almost the same as those of ZnO. This coincidence implies that the ZnO electronic structure was partially formed in the nanocomposites. Two structural possibilities were discussed for the nanocomposites.
