ABSTRACT:
A luminescent screen includes a luminescent zeolite containing rare earths, such as terbium (Tb), and europium (Eu), and an oxide of a transition metal, such as, molybdenum (Mo), tungsten (W), niobium (Nb), and tantalum (Ta). It was found that a zeolite containing both terbium, and tungsten oxide had an absorbability that was approximately 60 times as high as that of a zeolite containing only terbium, thus increasing the luminescent efficiency of the zeolite.
