摘要
以乙二胺四乙酸(EDTA)为模板剂,采用水热法,成功地合成一系列具有较大长径比的一维GdV1-xPxO4∶Tm蓝色纳米荧光粉。利用X射线衍射仪、扫描电镜、荧光光谱仪对产物的相结构、形貌和发光性能进行了分析。结果表明所得产物均具有明显的一维特征,随P含量的增加,产物的长径比增加,纳米棒逐渐变细。产物在未经焙烧的条件下,在278nm波长紫外光激发下发出强度较高的波长为478nm的明亮蓝光,掺P摩尔比,即x=0.4时,所得产物的发光强度最好。
One dimensional GdV1-xPxO4 ：Tm blue luminescent nanomaterials with larger length-diameter rano were successfully synthesized by hydrothermal method with ethylenediamine tetraacetate （EDTA） as template. The phase structure, morphologies and luminescence properties of GdV1-xPxO4 ：Tm were investigated by Xray diffraction （XRD）, scanning electron microscopy （SEM） and photoluminescence spectroscopy（PL）. The results show that the products are all one dimensional. As the molar ratio of doping P（x） increasing,the nanorods become more slender and their length-diameter ratio gets larger. Without calcination, the products emit bright 478nm blue fluorescence when excited by 278nm ultraviolet radiation and the phosphor has the optimal property when x= 0.4.
