Abstract

By kinetically controlled vapor-diffusion catalysis, nanostructured ZnO and Zn5(OH)8(NO3)3*2H2O thin films have been grown on substrates with different chemical compositions and varying degrees of crystallinity. The materials resulting from heterogeneous nucleation under mild conditions (starting from aqueous metal salt precursor solutions at room temperature) were characterized by X-ray diffraction and scanning electron microscopy to determine the influence of the substrates on the overall chemical composition, crystallinity, and morphology of the films.

摘要

通过动力学控制的气相扩散催化，在具有不同化学组成和不同结晶度的基底上生长了纳米结构的ZnO和Zn5(OH)8(NO3)3·2H2O薄膜。在温和条件下（从室温下的金属盐水溶液前驱体溶液开始）通过非均相成核得到的材料，用X射线衍射和扫描电子显微镜进行了表征，以确定基底对薄膜整体化学组成、结晶度和形态的影响。
