锌片上多形貌ZnO微晶的水热合成及生长机理

本文采用水热法以锌片作为锌原料提供ZnO微晶生长的养料，在锌片上制备ZnO微晶。使用蒸馏水、NH3?H2O、NaOH和丁胺作为矿化剂，生长的水热环境呈碱性。实验表明，各种不同碱性矿化剂浓度、分子结构及矿化剂溶液的饱和蒸气压都显著地影响ZnO晶体的生长习性，使得样品的最终晶体形貌呈现不同的特点。研究中利用XRD中各晶面衍射强度值数据对晶体形貌特征进行推测，并以SEM进行形貌验证，同时探讨了以锌片为原料制备ZnO微晶的生长机理。

Hydrothermal Synthesis of ZnO Crystallite with Multi-morphology on Zinc Foil and Crystal Growth Mechanism

Using zincpieces as raw material to provide nourishment for ZnO crystal growth,ZnO crystal was synthesized on the zinc foils through hydrothermal method.Distilled water,NH3\5H2O,NaOH and ethylenediamine were used as mineralizer to keep hydrothermal environment as alkaline.The results showed that the concentration,molecular structure and solvent saturated vapor pressure of mineralizer affected the ZnO crystal growth habit remarkably,resulting in different final crystal morphologies.The feature of crystal mor...
