气－液界面Q－态CdS的生长

The formation of Q-State CdS at the Air-Water interface

通过对不同形成阶段气一液界面Ｌａｎｇｍｕｉｒ膜诱导下的ＣｄＳ粒子的研究，证实了气一液界面ＣｄＳ粒子点→网→片→交叠的形成过程，紫外可见吸收光谱分析表明这种ＣｄＳ粒子具有量子尺寸效应，相对于体相带隙蓝移０．１５ｅｖ．

It was prived that the formation process of the CdS induced by iangmuir films at the air-water interface was dots-net -piece-piece by piece after system research of our group.The quantum size affect of this CdS was observed and there were a blue shift about 0.15ev of the band gap of this CdS compared with that of bulk CdS crystal.
