Abstract
There is provided a method of making a SrBO:Pb phosphor that increases the manufactured quantity of the SrBO:Pb phosphor by approximately seven fold when using the same size reaction vessel, decreases the lead-containing waste stream, and eliminates the use of hazardous concentrated ammonium hydroxide. The UV emission brightness is equivalent to or better than the same phosphor when prepared using prior methods.
