日本专利:东芝公司研制的这种阴极射线管采用掺杂强磁性金属的绿光发射材料(Ⅰ)和类似的非掺杂材料(Ⅱ)材料(Ⅰ)的平均粒径约为6—15微米并用0.1——500ppm 的 Te,Ca 和 Ni 中的至少一种掺杂。材料(Ⅱ)的平均粒径约为3—9微米。材料(Ⅰ)与材料(Ⅱ)的混合比为100pt s.wt.比1—50pt s.wt 绿光发射材料基质包括 ZnS:Cl,Al;(ZnCd)S:Cu,Al;ZnS:Au,Al。由散射电子和反射电子而引起的荧光基质材料的无规则发射得到了改善,使这种阴极射线管的亮度和对比度都有很大提高。
Japanese Patent: Toshiba developed such a cathode ray tube using a ferromagnetic metal-doped green light emitting material (I) and a similar non-doped material (II) material (I) having an average particle size of about 6-15 microns And doped with at least one of 0.1 - 500 ppm of Te, Ca and Ni. The average particle diameter of material (II) is about 3-9 microns. The mixing ratio of the material (I) to the material (II) is 100 pts s.wt. to 1 to 50 pts.wt. The green light emitting material matrix includes ZnS: Cl, Al, (ZnCd) S: Cu, Al, ZnS: Au, Al. The irregular emission of the fluorescent host material caused by the scattered electrons and the reflected electrons is improved so that the brightness and the contrast of the cathode ray tube are greatly improved.
