| 摘 要： | 采用水热法制备了不同形貌的GdVO4:Eu3+纳米晶样品,对其结构以及发光性质进行了表征。XRD结果表明:水热前驱体和经过灼烧之后样品均为四方晶系,具有锆石结构。TEM照片表明:通过改变表面活性剂分别得到了分散性良好的米粒状、六角形和球形的GdVO4:Eu3+纳米晶粒子。发光光谱表明:在288nm的紫外光激发下,不同形貌的GdVO4:Eu3+纳米晶材料均在617nm处产生特征红光发射,归属为Eu3+离子的5D0→7F2跃迁,不同形貌粒子的发光光谱的相对强度有所不同。

| Abstract: | GdVO4 ∶ Eu3+ luminescent nanomaterials with different morphologies were prepared by hydrothermal method, and their structure and luminescent properties were characterized. XRD patterns showed that the precursors and the heat-treated samples are tetragonal phase GdVO4 crystals. TEM images indicated that the rice-shaped, tetragonal-shaped and spherical GdVO4 ∶ Eu3+ nanoparticles were obtained by changing different surfactant. Fluorescence spectra showed that under the excitation of 288 nm, GdVO4 ∶ Eu3+ nanomaterials with different morphologies have the characteristics of red emission in 617nm, attributing to the 5D0→7F2 transition of Eu3+, the intensities of the fluorescence spectra are different for different samples prepared with different surfactants. |
