Abstract

Abstract This invention relates to a photoconductor element primarily consisting of (Zn1-y Cdy Te)1-z (In2 Te3)z, wherein o < y < 1, o < z < 1, or a photoconductor element comprising hetero-junction of material primarily consisting of Zn1-x Cdx S, wherein o < x < 1 and material primarily consisting of (Zn1-y Cdy Te)1-z (In2 Te3)z wherein o < y < 1, o < z < 1, which has a high light sensitivity over entire visible light range particularly in blue range and which is suitable for a target of a color image pickup tube.
