Method for producing europium activated yttrium vanadate phosphor |
| abstract |
A HIGHLY PURE AMMONIUM METAVANADATE WITH IMPROVED PARTICLE SIZE AND BULK DENSITY IS PRODUCED FROM AN INPURE AMMONIUM METAVANADATE BY DISSOLVING THE INPURE AMMONIUM MATAVANADATE IN WATER, MAINTAINING CONTROLLED TEMPERATURE CONDITIONS FOR A PERIOD OF TIME, FILTERING, MAINTAINING THE FILTRATE UNDER CONTROLLED PH AND TEMPERATURE CONDITIONS FOR A SPECIFIED PERIOD OF TIME, CRYSTALLIZING SOLID AMMONIUM METAVANADATE, WASHING THE CRYSTALS WITH WATER, VACUUM DRYING UNDER CONTROLLED TEMPERATURE AND HEAT TREATING UNDER AGITATION AND CONTROLLED TEMPERATURE CONDITIONS. THE METAVANADATE IS FIRED WITH A YTTRIUM AND EUROPIUM SOURCE TO PRODUCE A EUROPIUM ACTIVATED YTTRIUM VANADATE PHOSPHOR. |
