| titleOfInvention | Rare earth oxybromide phosphor |
| abstract | PURPOSE: The title phosphor with enhanced luminance and moisture resistance, comprising a matrix consisting of (Y 1-x Gd x )OBr and an activator consisting of Ce. n CONSTITUTION: After ammonia water is added to a soln. of Y and/or Gd oxide in nitric acid to adjust the pH, Ce(NO 3 ) 4 and oxalic acid soln. are added to coprecipitate rare earth oxalates, which are thermally decomposed to obtain Y and/or Gd oxide doped with Ce. The oxide is fired after addition of NH 4 Br at 400W600°C for 1W2hr and then further fired after addition of additional NH 4 Br in the presence of a reducing agent such as active carbon at 1,000W1,200°C for 1W3hr to obtain a phosphor of the formula (Y 1-x Gd x )OBr:Ce(wherein 0.05≤x<0.80). n COPYRIGHT: (C)1986,JPO&Japio |
