| titleOfInvention | Method for producing zinc sulfide phosphor |
| abstract | The present invention relates to a method for producing a zinc sulfide-based phosphor by firing a zinc sulfide-based phosphor precursor, and a first firing step of firing a mixture containing the phosphor precursor, sulfur and a chlorine-containing flux. Then, the mixture is heated to raise the temperature from room temperature to a temperature at which the phosphor precursor crystal system transitions, in an atmosphere in which oxygen is introduced, and then from above the transition temperature, the atmosphere Is switched to a nitrogen atmosphere and heating is further continued. When the temperature reaches 1000 ° C. or higher and 1200 ° C. or lower, the temperature is kept constant, and then the mixture is rapidly cooled and washed to obtain a fired product. In the second firing step of further firing the fired product obtained from the first firing step, the fired product obtained in the first firing step is heated in a nitrogen atmosphere to 650 ° C to 1000 ° C from room temperature. To a temperature of Time holding the temperature while introducing oxygen at reaching the and then quenched calcination was washed to provide a manufacturing method characterized by obtaining a zinc sulfide based phosphor. |
