有机锡化合物已成功用于在玻璃基板上制备高取向的 SnO2 薄膜。四正丁基锡(IV)和二正丁基锡(IV)二乙酸酯的喷雾热解分别导致[110]-和[200]取向的SnO2薄膜的沉积。这些薄膜的定向生长经历了三个阶段：(1) SnO2 核的形成，(2) 具有择优取向的 SnO2 晶体生长，以及 (3) 垂直于基底表面的进一步晶体生长。有机锡化合物的丁基和乙酰氧基分别促进SnO2薄膜的[110]-和[200]-取向生长。本模型根据起始化合物的分子结构与生长表面的原子构型之间的关系解释了 SnO2 薄膜的定向生长。
Organotin compounds were used successfully to prepare highly oriented SnO2 thin films on glass substrates. Spray pyrolysis of tetra-n-butyltin(IV) and di-n-butyltin(IV) diacetate led to the deposition of [110]- and [200]-oriented SnO2 films, respectively. The oriented growth of these thin films occurred via three stages: (1) formation of SnO2 nuclei, (2) crystal growth of SnO2 with preferred orientations, and (3) further crystal growth normal to the surface of the substrate. The butyl and acetoxy groups of the organotin compounds facilitated [110]- and [200]-oriented growth of SnO2 thin films, respectively. The present model explains the oriented growth of SnO2 thin films in terms of the relationship between the molecular structure of the starting compounds and the atomic configuration of the grown surfaces.
