    摘要: Disclosed is a novel cathode ray-luminescent phosphor which is a composite body consisting of a dealuminized zeolite carrying a specified amount of a metal such as tin, cobalt and nickel or an oxide thereof within the pores of the dealuminized zeolite structure. The cathode ray-luminescent phosphor is prepared by a method comprising the steps of: (a) heating an ammonium-form zeolite in the presence of steam to effect dealuminization of the zeolite; (b) impregnating the dealuminized zeolite with an aqueous solution of a metal salt in an amount of the metal salt in the range from 10 to 60 parts by weight calculated as metal per 100 parts by weight of the dealuminized zeolite; (c) drying the dealuminized zeolite impregnated with the aqueous metal salt solution; and (d) calcining the dried zeolite in a reducing or oxidizing atmosphere at a temperature in the range from 450 to 600.degree. C. for 1 to 5 hours to form a composite of the dealuminized zeolite and the metal or an oxide of the metal, respectively.
