用LB膜技术在石英及CaF2衬底上沉积二十二酸锌Y型多层膜,低压(66.7Pa)下与H2S气体反应。红外、可见紫外吸收光谱及X衍射结果表明,反应前后LB膜仍保持良好的有序性。反应后生成的ZnS超微粒子以“三明治”结构存在,并观察到这种ZnS纳米微粒以单分子膜状态存在。
The LB film technique was used to deposit zinc docosanoate Y-type multilayers on quartz and CaF2 substrates and react with H2S gas at low pressure (66.7 Pa). Infrared and visible UV absorption spectra and X-ray diffraction results showed that the LB films remained well ordered before and after the reaction. The ZnS nanoparticles produced after the reaction exist in a “sandwich” structure and the existence of the ZnS nanoparticles in a monomolecular state is observed.
