| 摘 要： | 采用微乳液法制备了Fe掺杂ZnO纳米球材料(Zn1-xFexO,x=0.1),利用XRD和TEM对制备样品的结构、形貌进行了表征。在室温下,测得材料宽化的吸收光谱。用325nm的激光激发,测量了ZnO纳米球的光致发光光谱,低强度激发时观察到半峰全宽较窄、峰值波长为385nm的紫光峰和半峰全宽较宽、峰值波长约625nm的深能级发光峰;两峰的发光强度和峰位随着激发光功率密度的变化而变化,但变化规律不同。所合成材料的吸收和发光性质与Fe掺杂相关。

| Abstract: | Fe-doped ZnO nanoballs Zn1-xFexO,(x=0.1) are prepared by microemulsion route. X-ray diffraction (XRD) and transmission electron microscope (TEM) are used to characterize their structure and morphology. Widen absorption spectrum is measured at room temperature. Exciting with 325 nm laser, the photoluminescence includes violet part peaked at 385 nm and widen visible emission peaked at about 625 nm at low excitation power, and the emission intensities and peak positions of these two parts change along with the laser excitation power density. Absorption and photoluminescence properties of the products are both relevant to Fe-doped situation. |
