Abstract:
A phosphor made by performing the steps of:a) mixing a quantity of zinc oxide (ZnO) with a quantity of tantalum pentoxide (Ta.sub.2 O.sub.5) to form a mixture;b) adding a quantity of water to said mixture to form a slurry;c) ball milling and drying said slurry to provide a dry intermediate mixture;d) heating said dry intermediate mixture at 900.degree. C. or higher;e) granulating the resultant material to a fine powder;f) mixing an organic polymer with said fine powder as a binder;g) pressing the resultant material into a solid mass; and then firing said solid mass at a effective temperature and time at 900.degree. C. or higher for at least about 1 hour to form Ta.sub.2 Zn.sub.3 O.sub.8.
