| 摘要: 利用柠檬酸配合法合成了一种新型的自激活白光发射荧光材料Ba2TiP2O9，通过热重-差热、X射线粉末衍射、光致发光光谱、色坐标、X射线光电子能谱以及热释发光等手段对样品进行了表征。分析结果表明，通过柠檬酸配合方法制得的Ba2TiP2O9自激活荧光材料在800 ℃烧结3 h即可获得良好的发光性能。在254 nm紫外线激发下，可产生明亮的白光发射。其色坐标值分别为x=0.27，y=0.35。所得样品的白光发射来源于Ti-O之间的电荷转移。 |

| Abstract: The novel self-activated white-light-emitting luminescent material Ba2TiP2O9 has been prepared by the citric-complex method. The synthesized materials were characterized by XRD (X-ray Diffraction), TG-DTA (Thermogravimetry/Differential Thermal Analysis), photoluminescence, colour coordinates, XPS (X-ray Photoelectron Spectrometer) and thermoluminescence spectra. XRD confirmed that the as-synthesized materials under 800 ℃ for 3 h were pure phase of Ba2TiP2O9. The as-synthesized materials showed strong white-light emittion arising from the Ti-O charge transition when under 254 nm UV light irradiation. The white-light-emitting from the Ba2TiP2O9 is located at a colour coordinate with x being 0.27 and y being 0.35. |
