Encapsulated phosphor with reduced surface area |
摘要 |
A method of reducing the surface area of an encapsulated phosphor includes the steps of preparing a homogeneous mixture of an encapsulated phosphor and a surface area reducing agent selected from the group consisting essentially of boric acid and ammonium dihydrogen phosphate and firing the mixture for a time and at a temperature to reduce the surface area of the encapsulated phosphor.
