摘要:
采用热液法制备ZnO晶体材料,分别在空气、N2和水蒸气条件下进行退火处理。采用扫描电子显微镜(SEM)、X线衍射仪(XRD)、紫外-可见分光光度计(UV-vis)和荧光分光光度计(PL)考察不同退火处理对ZnO结构和光学性能的影响。结果表明:热液法制备的ZnO呈六角相棒状形貌,棒直径约为2 μm,长度约为10 μm。经3种退火方法处理的样品的形貌和尺寸没有明显变化,取向性和结晶度都有所改善,透光率升高,光致发光近带边发射峰强度增大。相比ZnO体材料的紫外吸收(380 nm),处理后样品出现了轻微蓝移现象。初步探讨了不同退火处理方法改善ZnO晶体材料光学性能的机制。
Abstract:
ZnO crystals were prepared by hydrothermal method and subsequently annealed in air,nitrogen and water vapor,respectively.The effects of the treating methods on crystal structures and optical properties of ZnO crystals were investigated by scanning electron microscopy(SEM),X-ray diffractometer(XRD),ultraviolet-visible-near infrared spectrophotometer(UV-vis)and photoluminescence spectroscopy(PL).Results indicated that the prepared samples were rod textures.The length of ZnO nanorods was about 10 μm and the diameter was about 2 μm.No obvious distinction was observed in the morphology and size of the treated ZnO samples.The crystal quality and optical properties of ZnO were improved and the transmittance was enhanced by different treating methods.The near band gap peak intensity of the treated samples was enhanced.The UV-vis absorption spectra showed that the UV emission peak position of the treated ZnO samples had blue shift to higher energy level to bulk ZnO.The improvement mechanism for optical properties of the treated ZnO crystals was discussed.
