摘要

采用了放射性同位素氚在衰变过程中放射出β粒子激活发光材料发光的原理。因β粒子平均自由程只有4.3 mm

灯型选择直径应在4~8 mm之间。通过实验比对

确定常用的发光材料为:发红光材料硫氧钇 : 铕(Y

S : Eu);发绿光的发光材料硫化锌 : 铜

铝(ZnS : Cu

Al);发蓝光的发光材料硫化锌 : 银(ZnS : Ag)。经过测试选择发光材料的最佳平均粒度:硫氧钇铕4.6 μm;硫化锌铜铝5.3 μm;硫化锌银5.4 μm。同时探讨了涂屏方法和充氚排气工艺。对制作的氚灯进行了光亮度测试。最后给出了氚灯的使用与保存方法。

Abstract

The principle of activating the phosphors to luminescence by β particle emitted from tritium isotope was introduced. Because the average free path of β-particle is only 4.3 mm

the diameter of the lamp is limited between 4 mm and 8 mm. From experiment

we can come to the conclusions as follows:First

S : Eu is the familiar phosphors which can emit red ray. Secondly

ZnS : Cu

Al is the familiar phosphors which can emit green ray. Finally

ZnS : Ag is the familiar phosphor which can emit blue ray. From testing

the optimal granularities of Y

S : Eu

ZnS : Cu

ZnS : Ag are 4.6

5.3 and 5.4 μm

respectively. The methods of phosphor coating and the technics of charging the tritium are introduced in detail. The brightness of the tritium lamp was also tested. At last

the methods of using and storage of tritium lamp were explained.
