气相法制备中，纳米材料的生长行为受到多个实验参数影响，在目前"实验参数-生长行为"多对一的调控生长模式下，制备可控性较差。在前期研究基础上，本项目提出实验参数通过影响饱和度进而改变纳米材料生长行为的新观点，以ZnO、In2O3为研究对象，设计实验考察饱和度对反应物分子成核、吸附迁移及晶面生长行为的影响规律；基于规律，设计合成分级结构、不同指数暴露晶面以及自组装等新奇纳米结构，探索饱和度控制下的可控制备路径；并进一步开展形貌、暴露晶面、掺杂与光致发光性能之间的构效关系研究。项目中饱和度调控生长规律的探索，为气相法中可控制备提供了新的思路，同时新奇纳米结构的构筑及其光学性能的研究也将为纳米光学器件提供新的结构体系。因此，该项目的开展对推动气相法在纳米制备科学中的发展具有重要的意义。

In the vapor route, the growth behavior of nanostructure is controlled by numerous experimental parameters, such as heating temperature, precursor, carrying gas and others. It is one challenge to realize controlled growth under present growth mode controlled by multiple experimental parameters. Focusing on this question, a new viewpoint, the growth behavior can be modulated by the supersaturation ratio affected by the experimental parameters, is proposed in this work based on our previous researches. Herein, ZnO and In2O3 are selected as research objects. First, the growth rule of nucleation, adsorption, migration and incorporation into crystalline plane controlled by reagent's supersaturation ratio is investigated. Second, based on the growth rule, nanoarchitectures of different novel nanostructure, viz. hierarchical, exposed with different crystalline planes and self-assemble nanostructures, attempts to prepare aiming to exploit the synthesis approach of nanostructure controlled by supersaturation ratio. Third, utilizing above prepared nanostructure, the relationship between structural characteristics, viz. morphologies, exposed crystalline planes and doped agents, and photoluminescence property is explored; In a word, our research on growth rule will shin a light on controlled synthesis in vapor route. And then, the investigation of architecture and their photoluminescence properties provide new structure system for optical nano-devices. So, the process of this project will promote the development of vapor synthesis in nanoscience.
