Method of phosphor preparation |
| abstract |
An improved method for preparing a phosphor is disclosed. The method of the invention includes preparing a solution comprising the non-oxygen elements of the phosphor in molar proportions equal to the respective molar proportions of the non-oxygen elements in the phosphor; precipitating the non-oxygen elements from the solution through the addition of a precipitating agent; spray drying the solution including the precipitate to form a spray dried powder; and firing the spray dried powder in a single firing step. The single firing step of the method comprises (a) increasing the temperature of the spray dried powder at an even and controlled rate from room temperature to a firing temperature sufficiently high to convert the spray dried powder to the phosphor; and (b) maintaining the temperature of the spray dried powder at the firing temperature for a period of time sufficient to produce the phosphor. The method is particularly useful in the preparation of Eu 2+ -activted strontium borate phosphor. |
