| 摘 要： | 利用高分子包覆法(Polymer Capping Method)在Si衬底上生长了颗粒分布均匀、致密的纳米ZnO薄膜.样品的形貌和光学性能分别使用SEM,AFM和PL谱进行表征.实验发现,前驱体溶液的pH值对纳米颗粒的分散性和尺寸有很大影响,进而影响紫外发光峰位.在本实验条件下,随纳米颗粒尺寸增大,PL谱的紫外发光峰红移,符合量子尺寸效应.

| Abstract: | Uniform and compact ZnO nano-particles were synthesized on Si substrate via a polymer capping method.The morphology and optical property of as-synthesized samples were characterized by SEM,AFM and PL spectra.It was observed that pH value of the precursor had a great effect on the dispersibility and size of the nano-particles,which further induced a change of the peak position of the PL spectra in ultraviolet range.In detail,experiment results indicated that the PL spectra peaks in ultraviolet range had a re... |
