An electroluminescent phosphor with an extended half-life is created by means of the present invention by taking an amount of a phosphor and treating it with antimony comprising the steps of placing an amount of antimony in an inert reaction vessel, placing a vapor permeable filter on top of the antimony, placing a phosphor with a given half-life on top of the vapor permeable filter, evacuating the reaction vessel below one atmosphere and heating it for a period of time to allow the antimony to react with the phosphor to produce a new phosphor with an extended half-life.
