    摘要: A photoconductive film comprising a photo-conductive layer which is mainly made of selenium and a region added with tellurium in a direction of the thickness of the layer, wherein at least either one of a portion in a direction of hole flow of said region added with tellurium and a portion in the hole flow of another region which is located adjacent to said region added with tellurium is doped with at least one member selected from the group consisting of an oxide, a fluoride and elements which belong to the group II, III and VII, which are capable of forming a negative space charge in selenium, at a concentration in a range of 10 ppm to 1% by weight on an average. Typical examples of such oxide, fluoride and element include CuO, In.sub.2 O.sub.3, SeO.sub.2, V.sub.2 O.sub.5, MoO.sub.3, WO.sub.3, GaF.sub.2 InF.sub.3, Zn, Ga, In, Cl, I, Br and the like. The after image characteristic ascribable to incident light of high intensity can be significantly improved.

    摘要: A photoconductive image pick-up tube target comprises a transparent substrate, an N-type conductive film formed on the transparent substrate, and a P-type photoconductive film in rectifying contact with the N-type conductive film and containing Se, As and Te as sensitizer. The P-type photoconductive film includes a first layer contiguous to the N-type conductive film and containing 94.+-.1% by weight of Se and 6.+-.0.5% by weight of As, a second layer formed on the first layer and containing 64.+-.4% by weight of Se, 3.+-.0.5% by weight of As, and 33.+-.2% by weight of Te, a third layer formed on the second layer and containing Se and As, and a fluoride doped region extending over the first layer and a front half layer of the second layer and having a fluoride concentration of 0.1 to 3.0% by weight. The third layer has an As concentration which has a peak of 28.+-.1% by weight at a site contiguous to a rear half layer of the second layer and reduces gradually.
