摘要:

采用液相沉积法在云母基材表面双层包覆二氧化钛和镨掺杂氢氧化钙, 经高温煅烧在两层之间生成镨掺杂钛酸钙(CaTiO3:Pr3+)荧光层。通过荧光分光光度计、全自动色差计、X射线粉末衍射仪和冷场扫描电子显微镜测试样品的性能。结果表明, 当氧化钙理论包覆率为5.3%、镨浓度相对硝酸钙为0.2mol%、煅烧温度为900℃时, 样品表面均匀、致密, 具有较好的珠光性能和荧光强度, 样品的激发光谱由264、304和380 nm三个激发峰组成, 最大发射波长主峰位于613 nm, 呈红光发射, 对应于Pr3+1D23H4跃迁。

Abstract:

Double-layer of titanium dioxide and Pr-doped calcium hydroxide were coated on the surface of mica by liquid phase deposition, and followed by calcination to form the Pr-doped calcium titanates fluorescent layer. The resultant CaTiO3:Pr3+/TiO2-mica fluorescent pearlescent pigments were characterized by photoluminescence excitation (PLE) and emission (PL), automatic colorimeter (AC), X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM), respectively. The fluorescent pearlescent pigments obtained at the calcium oxide cladding ratios of 5.3%, the praseodymium/calcium nitrate molar concentration of 0.2%, and the calcinations temperature of 900 ℃, show good pearl property with homogeneous, dense and smooth surface, and relatively high fluorescence intensity. The excitation spectrum of these fluorescent pearlescent pigments consists of three bands at 264, 304 and 380 nm. The maximum emission wavelength is found to be a red light of 613 nm, corresponding to the transition for 1D23H4.
