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, Y_2O_2S: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_2O_2S:Eu, ZnS:Cu,Al, 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.
