METODO PARA FABRICAR UN MATERIAL FOSFORESCENTE DE SILICATO DE CINC. |
摘要 |
Improved zinc silicate phosphor particles are made by using silicic acid particles in the range from 0.7 to 10 micrometers coated with Mn2O3xxH2O and then a layer of ZnO particles about an order of magnitude smaller which are fired to form the phosphors. The particle size is held within the range preferred and preferably is even narrower. The particles are not milled or mechanically crushed. Instead, the ZnO powder prevents agglomeration during firing. Baths are provided for formation of the particles prior to firing. Brightness and persistance are improved over conventional phosphors. |
