PROBLEM TO BE SOLVED: To provide a luminescent ultraviolet shielding material which, while keeping a shielding property of undesired ultraviolet rays, makes reuse of the shielded and absorbed ultraviolet rays as light externally and improves efficiency in a visible light region, and provide a luminescent ultraviolet shielding filter, a lamp and a lighting apparatus using the luminescent ultraviolet shielding material. SOLUTION: The luminescent ultraviolet shielding material 1 is composed of luminescent particulates made from a zinc oxide as main composition, which is doped with at least one of tungsten, manganese or europium, having its peak at 450 to 550 nm by ultraviolet rays, and a luminescent ultraviolet shielding filter, a lamp and a lighting apparatus using the luminescent ultraviolet shielding material are provied.
