摘要: 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。

Abstract: Zinc pieces were adopted as raw material to provide nourishment for ZnO crystal growth, ZnO crystal has synthesized on the zinc foils through hydrothermal method. Distilled water, NH3?H2O, NaOH and butyl amine were used as mineralizer to keep hydrothermal environment as alkaline. The results show that ZnO crystal growth habit affect by concentration; molecular structure and solvent saturated vapor pressure of mineralizer remarkably, make the final crystal morphology difference. In the study, the author also speculated on the feature of crystal morphology by XRD data of diffraction intensity of crystal plane and validated by scanning electron microscope (SEM). Moreover, crystal growth mechanisms of ZnO crystallite on the zinc foil were discussed in detail.

Key words: Hydrothermal method, Zinc oxide crystallite, Crystal growth mechanism, Mineralizer, Diffraction intensity of crystal plane
