【摘要】 <正> 由于5s壳层的屏蔽,Tb³⁺离子的4f电子跃迁产生的发光,其波长受基质的影响很小,而发光强度却与基质材料、Tb³⁺离子的浓度有密切的关系。Tb³⁺离子激活的硅酸盐发光材料在专利中曾有报导,但Tb³⁺离子在ⅡA、ⅡB族硅酸盐中的发光行为尚未见报导。我们在过去工作的基础上,合成了Tb³⁺离子激活的ZnO-SrO-SiO₂发光材料。更多还原

【Abstract】 Luminophores of （Zn-Sr）₂SiO₄:Tb³⁺ were synthesized at high tepsperature usingSrCO₃, ZnO, SiO₂, Li₂CO₃ and Tb₂（C₂O₄）3 as raw materials. Optimum conditions,judged by the relative intensity of illumination, were found by orthogonal design, i.e.1200℃, Zn:Sr = 0.75:0.25, SiO₂ = 3.0 mol, Tb = 0.1 mol. The properties of the producthas been examined by means of x-ray powder diffraction and fluorescent spectra.更多还原
