| 摘 要： | 采用均匀沉淀法在常温开放体系下制备了片状ZnO晶体前驱物,经600℃煅烧得到纯ZnO晶体;在此基础上,采用原位掺杂的方法制备了片状掺Fe的ZnO晶体。通过体视显微镜、XRD、UV-Vis吸收和PL研究了Fe掺杂对片状ZnO晶体结构和光学性能的影响。结果显示掺Fe后ZnO晶体仍具有正六边形形貌和纤锌矿结构,其在398nm处的紫外发射峰和458nm处的蓝光发射峰位置保持不变,但晶片直径减小,禁带宽度增大,发光峰强度降低。

| Abstract: | Sheet-like ZnO crystal and sheet-like Fe-doped ZnO crystal were prepared by homogeneous precipitation method and in-situ doping method in room temperature under open system,respectively.In order to investigate the influence of Fe-doping to ZnO,we used stereomicroscope,X-ray diffractometer,fluorescence spectroscope and ultraviolet-visible-near infrared spectrophotometer to express the structure and optical properties of the samples.The result indicated that pure ZnO and Fe-doped ZnO both have hexagon shape,w... |
