    • New x-ray photoconductive compositions are disclosed which are certain composites containing (1) inorganic clusters of VB-VIB semiconductors, VB-VIIB semiconductors, IIB-VIB semiconductos, IIB-VB semiconductors, IIIB-VB semiconductors, IIIB-VIB semiconductors, IB-VIB semiconductors and/or IVB-VIIB semiconductors and (2) polymers which are essentially non-carrier-transporting in the absence of x-rays. Also disclosed is an x-ray radiograpy apparatus which employs an image receptor which is a composite of certain inorganic clusters and polymers. A method is disclosed for enhancing the x-ray absorbing efficiency of a polymer which is essentially non-carrier transporting in the absence of x-rays and the x-ray photoconductivity of said polymer by doping the polymer with an effective amount of clusters having a size within the range of from about 0.001 .mu.m to 10 .mu.m.
    • 公开了新的x射线光电导组合物,它们是含有(1)VB-VIB半导体的无机簇,VB-VIIB半导体,IIB-VIB半导体,IIB-VB半导体,IIIB-VB半导体,IIIB-VIB半导体,IB -VIB半导体和/或IVB-VIIB半导体和(2)在不存在x射线的情况下基本上是非载流子传输的聚合物。 还公开了一种使用作为某些无机簇和聚合物的复合材料的图像受体的X射线放射治疗装置。 公开了一种提高聚合物的X射线吸收效率的方法,该聚合物在不存在x射线的情况下基本上是非载流子传输的,并且所述聚合物的X射线光电导率通过用有效量的聚簇掺杂聚合物而具有 尺寸在约0.001微米至10微米的范围内。
