超声化学法硒纳米晶体的可控制备

Sonichemical method to prepared morphology-controlled selenium nanocrystals

超声化学法,制备Se纳米棒(线),产物由x-射线衍射仪、扫描电镜进行了表征.讨论了反应的浓度、时间对纳米晶形状的影响.实验证明,Se纳米晶的直径随着反应浓度的增加而增大,Se纳米晶的长度随着反应的时间延长而增大.

Selenium nanorods and nanowires were prepared by soniehemical method. The products were characterized by XRD, SEM. The diameters of selenium nanocry stals increase with the reagent concentration, and the lengths of selenium nanocrystals increase with the reaction time under the experiment conditions. And the effect of reaction time and precursor concentration to the morphology of nanocrystals were discussed.
