摘要：用离子交换法制备ＣｄＳ／ＰｂＳ复合超微粒，用ＬＢ膜技术进行有序组装。ＣｄＳ／ＰｂＳ复合超微粒的吸收光谱介于ＣｄＳ和ＰｂＳ超微粒的吸收光谱之间。ＣｄＳ／ＰｂＳ超微粒／硬脂酸ＬＢ膜具有层状结构，吸收光谱和荧光光谱发生明显变化。ＣｄＳ／ＰｂＳ复合超微粒是以ＣｄＳ为核心，ＰｂＳ为壳层的表面包裹结构。在ＣｄＳ比例较高和适当表面压下。
The CdS/PbS composite ultrafine particles were prepared by ion exchange method and orderly fabricated with LB film technique.The absorption spectrum of CdS/PbS composite ultrafine particles standed between the absorption spectrum of CdS ultrafine particles and that of PbS ultrafine particles.CdS/PbS ultrafine particles/stearic acid composite LB films had lamellar structure and their absorption spectrum and fluorescence spectrum obviously changed.CdS/PbS composite ultrafine particles had surface package structure of CdS center with PbS shell.CdS/PbS composite ultrafine particles were regularly arranged at higher content of CdS and under suitable surface pressure.
