By means of the LT representation the author calculated the energy levels and the splittings of sharp lines in ruby. The interaction between various configurations has been taken into account. The splittings of energy levels of R and B lines so obtained agree well with experimental results. But the splitting of ground state comes out too small to be compared with experiment. If may be attributed to the perturbation of the higher energy levels. .

本文采用LГ表象,考虑到不同组态间的相互作用(立方场,三角场与自旋轨道作用),计算了红宝石中锐线B,S与R线的能级及其分裂和基态的分裂。 所得结果是B线与R线跟实验较符合,基态的分裂较实验值小,这可能是更高能级的三角场与自旋轨道的微扰作用所引起的。

The CL spectrum consists of three groups of discrete sharp lines which is characteristic of Dy3+ ion 4f-4f transfer appearing yellow-white in color. The CL brightness is comparable to commercial MgF2:Mn2+(P33),or about 60% that of Zn2SiO4:Mn2+ ,As(P39).The SrAl2O4: Dy3+ phosphor shows a decay time of more than 200ms to decrease to an intensity of 1/10 of its initial value after the removal of CR...

A new synthetic cathodoluminophor with long Persistence, Dy3+ activated SrAl2O4 is presented in this Paper. The CL spectrum consists of three groups of discrete sharp lines which is characteristic of Dy3+ ion 4f-4f transfer appearing yellow-white in color. The CL brightness is comparable to commercial MgF2:Mn2+(P33),or about 60% that of Zn2SiO4:Mn2+ ,As(P39).The SrAl2O4: Dy3+ phosphor shows a decay time of more than 200ms to decrease to an intensity of 1/10 of its initial value after the removal of CR excitation of 10kV, 1μA/cm2 and the luminescence decay is nonexponential. Thermoluminescence of CR excitation shows the existence of deep traps which are responsible for the slow decay.Finally the model of luminescence decay in this phosphor is proposed according to experimental results.

本文介绍了一种新合成的长余辉阴极射线磷光体——SrAl_2O_4:Dy~(3+)。在室温下,用10kv、1μA/cm~2阴极射线激发磷光体时,其发射光谱由三组分立的锐线构成,系属Dy~(3+)离子4f—4f跃迁的特征发射;发光呈黄白色,发光亮度可以同商用MgF_2,Mn~(2+)(P33)相比较,大约为Zn_2SiO_4:Mn~(2+)、As(P39)亮度的60%。当阴极射线激发去除以后,磷光体的发光强度衰减到起始值的1/10的时间(通称余辉时间)长达200ms以上。发光衰减是非指数式的。阴极射线激发以后的热释发光表明:在磷光体中存在着构成慢衰减过程的深陷阱。 最后,根据实验结果,提出了这种磷光体发光衰减过程的物理模型。

Pure BaFCl has been obtained by the homogeneous precipitation from solutions of BaCl2 and NH4F.Pure CaFCl has been synthesized by the solid state reaction between anhydrous CaCl2 and CaF2. Samples of the system Ba1-xCaxFCl were prepared by firing the blended mixtures of appropriate amount of BaFCl and CaFCl.The phase diagram and the subsolidus relationship of the system Ba1-x, CaxFCl have been studied by the thermal analysis and by the lattice parameter determinations respectively.In this system there exists a compound of Ba0.5Ca0.5FCl,which incongruently melts at 804℃.The Eu2+activated samples of this system were prepared by heating Ba1-xCaxFCl with 1 mole% thoroughly mixed EuCl3 at 760℃ for half an hour. Meanwhile the EuCl3 undergoes a thermal reductive decomposition and thus formed Eu2 + ions incorporate into the host lattice and occupy the sites of Ba2 + or Ca2 + . The luminescent properties of these samples under the excitation of cathode ray,X-ray and UV(2537A) light were investigated.The luminescence spectra of these samples excited by X-ray(Cu,Ka, 50kV,20mA) consist of a sharp line emission peaking at 3630A(Eu2+ 6P7/2-8S7/2)and a band emission.The peak wavelengths of these bands shift from 3868A for BaFCl:Eu2+ to 4640A for CaFCl:Eu2 + . For the samples Ba1-x CaxFCl:Eu2 + with 0.7sharp line emission peaking at 3630A in the cathode ray luminescence spectra of the Ba-rich samples is due to the absorption of ultraviolet light by the lead glass window of the arrangement.

本文研究了Ba_(1-x)Ca_xFCl:Eu体系及其发光。从差热分析相图和X射线衍射分析发现在Ba_(1-x)Ca_xFCl体系中存在着Ba_(0.5)Ca_(0.5)FCl这个物相。Ba_(1-x)Ca_xFCl:Eu体系在X射线激发下的发光包含一个3630A的锐峰和一宽带发射峰,其峰值由BaFCl:Eu的3868(?)到CaFCl:Eu的4640(?),阴极射线和紫外线激发下的发射光谱与此类似。在X射线激发下,Ba_(0.8)Ca_(0.2)FCl:Eu的发光最强,而在阴极射线激发下,CaFCl:Eu的发光强度最大,在紫外线激发下,Ba_(1-x)Ca_xFCl:Eu的发光强度校弱。在以上三种激发情况下,Ba_(0.5)Ca_(0.5)FCl:Eu的发光都比较弱。
