摘要
探索了不同的生长时间、生长温度、气体和水分条件对采用热蒸发法生长CuO纳米线在成型、长度、致密度和直径等方面的影响。简单分析了CuO纳米线的生长过程、生长机理,并进一步研究了在CuO上生长ZuO量子点。通过改变实验条件,研究在不同温度、分解时间、乙酸锌浓度对ZuO量子点外形的影响。研究发现,生长温度会在一定范围内影响CuO纳米带的直径和致密度,时间会影响纳米线的长度。此外,在不同条件下可生成不同形状的ZnO纳米颗粒。这些参数条件对量子点的成核、生长和迁移有着至关重要的影响。
To explore the different growth time, temperature, gas and water conditions on the thermal evaporation method is used to grow CuO nanowires in shape, length, density and diameter, etc. Simple analysis of the CuO nanowires growth process, growth mechanism, and to further grow in the CuO ZuO quantum dot is studied. By changing the experiment condition, the research in different decomposition temperature and time, the influence of the concentration of zinc acetate ZuO quantum dot shape. The study found that growth temperature will affect the CuO nanoparticles within a certain scope of diameter and density;time will affect the length of the nanowires. In addition, produce different shapes under different conditions of ZnO nanoparticles. These parameters on nucleation, growth and migration of the quantum dots have very important influence.
