摘要

近年来

国际上纳米材料科学及其应用的研究非常活跃.纳米材料的尺寸效应和面效应与体材料相比有特殊的物理和化学特性

尤其是它的界面效应更为明显

因而米材料作为一种新兴的材料

受到了广泛的重视.但到目前为止

纳米材料的制备大采用化学合成的方法如悬胶法、凝胶-溶胶法等

而利用这些方法制备的纳米材料通常一定的尺寸分布

这主要是由于纳米材料在一定温度和时间下的凝结和分解等原因造的

[1]

因而严重地影响了纳米材料在各方面的特性.

Abstract

The CdS nanocrystals were grown in the SiO

molecular sieve by physics vapour transport for the first time. The PL spectra were measured at 77 K. The position the width and-the intensity of the emission band changed with increasing the growth time. These phenomena showed the formation process of CdS nanocrystal in SiO

molecular sieve. The emission band narrowing and confinement effect were observed.
