| titleOfInvention | Halophosphate phosphor |
| abstract | A halophosphate phosphor contains at least 80% by weight of spherical phosphor particles meeting the relationship of R </= R' < 1.5R, where R and R' represent the smallest and largest diameters of the phosphor particle, respectively. In an embodiment CaHPO4 coated with Sb4O5Cl2 is sieved, mixed with CaCO3, CaF2, NH4Cl, Sb2O3 and Mn(CO3)2, baked and powdered to give a calcium halophosphate phosphor activated by Sb and Mn and having the desired ratio of diameters. Metals to replace Ca are specified. |
