A photoresponsive device comprises s substrate (3), a hole blocking layer (15), an optional adhesive layer (6), an inorganic photogenerating layer (7), an organic photoconductive layer (9) sensitive to infra-red radiation, and a top coating (11) of a hole transport layer. More specifically, the present invention is directed to an improved photoresponsive device comprised in the order stated of the following layers: a conductive substrate (3), a metal oxide hole blocking layer (5), an adhesive layer (6), an inorganic photogenerating layer (7), a photoconductive composition (9) capable of enhancing or reducing the intrinsic properties of the photogenerating layer, which composition is selected from the group consisting or organic photoconductive compositions, charge transfer complex compositions, sensitizers, or mixtures thereof, and a hole transport (11). In an alternative embodiment, the positions of the photogenerating layer (7) and the photoconductive layer (9) are reversed.
光致发光器件包括基底(3)、空穴阻挡层(15)、可选粘合层(6)、无机光生成层(7)、对红外辐射敏感的有机光电导层(9)和空穴传输层的顶层涂层(11)。更具体地说,本发明涉及一种改进的光致发光器件,按所述顺序由以下各层组成:导电基板 (3)、金属氧化物空穴阻挡层 (5)、粘合剂层 (6)、无机光生成层 (7)、能够增强或降低光生成层固有特性的光电导组合物 (9),该组合物选自有机光电导组合物、电荷转移复合物组合物、敏化剂或其混合物组成的组,以及空穴传输层 (11)。在另一个实施方案中,光发生层(7)和光电导层(9)的位置是相反的。
