摘要：
A target of image pickup tube, which comprises a transparent substrate (1), a transparent conductive film (2), a p-type photoconductive film (3) made mainly from amorphous Se, an n-type conductive film capable of forming a rectifying contact at the interface with the p-type photoconductive film, using the rectifying contact as a backward bias, characterized in that the p-type photoconductive film (3) contains at least a region (b) containing over 35% to 60% by weight of Te in the film thickness direction and at least a region containing 0.005 to 5% by weight of at least a material capable of forming shallow levels in the amorphous Se in the film thickness direction, has good after-image characteristics even if operated at a high temperature (Fig. 2).
