ZnS超微粒有序组装体系制备与结构研究

The Study on the Preparation and Structure of ZnS Ultrasmall Partiles Organized Assembly System *

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。

Multilayers Zn(BA) 2 Y-typed films were deposited on the quartz and CaF 2 by LB technology,and reacted with H 2S gas in low pressure (66.7Pa).The results of the spectra of IR,UV-absorption and X-ray showed the LB film retained perfectly organized after reaction.ZnS nanoparticles exist in “sandwich” structures,and we first observed the ZnS nanoparticles presented in monolayer state.
