| titleOfInvention | Fluorescent material |
| abstract | PURPOSE: To provide a red light-emitting fluorescent material having improved luminance-saturation phenomenon in a high current-density range, and useful for a color CRT, displaying CRT, etc., by adding a specific small amount of Pr to a specific Eu-doped yttrium oxysulfide. n CONSTITUTION: (A) The fluorescent material of formula (0.0002≤a≤0.2) is doped with (B) 2W10ppm (preferably 4W8ppm) of Pr to obtain the objective fluorescent material. The fluorescent material can be prepared by (1) dissolving high-purity Y 2 O 3 and Eu 2 O 3 in concentrated hydrochloric acid, (2) diluting the solution with pure water, (3) adding a solution of praseodymium chloride to the mixture, (4) adding a solution of oxalic acid to effect the co-precipitation of the oxalates of Y, Eu and Pr, (5) collecting the precipitate by filtration, (6) converting the oxalate to oxide by heating at 800°C, and (7) calcining the product in the presence of S, Na 2 CO 3 , etc. n COPYRIGHT: (C)1986,JPO&Japio |
