有机光电探测器（OPD）是一种通过真空和溶液工艺制备的高速光电探测器。采用真空工艺，在ITO膜玻璃基片上用有机分子束沉积法（OMBD）制备了OPD。以酞菁铜（CuPc）和N，N '-二（2，5-二叔丁基苯基）-3，4，9，10-二萘嵌苯二甲酰亚胺（BPPC）为p型和n型材料。使用激光（λ=650 nm）评价OPD的光响应，并且在100 MHz下观察到清晰的响应信号。使用OPD成功接收成像信号。对于溶液处理的OPD，聚（9，9-二辛基芴）和磷光铱衍生物分别用作主体和掺杂剂材料。用真空处理和溶液处理的器件制作的OPD分别观察到100 MHz和大于40 MHz的脉冲信号。
Organic photo-detectors (OPDs) have been discussed as high-speed photo-detectors fabricated by vacuum and solution processes. By vacuum process, OPD was fabricated on an ITO-coated glass substrate by organic molecular beam deposition (OMBD). Copper phthalocyanine (CuPc) and N,N'-bis(2,5-di-tert-butylphenyl) 3,4,9,10-perylene dicarboximide (BPPC) were used as a p-type and an n-type material. The photo response of OPD was evaluated using a laser (λ=650 nm) and clear response signals at 100 MHz were observed. The imaging signals were successfully received using the OPDs. For solution processed OPDs, poly(9,9-dioctylfluorene) and a phosphorescent iridium derivative were used as a host and a dopant material, respectively. A pulsed signal of 100MHz and amore than 40 MHz were observed by the OPDs fabricated by the vacuum processed and the solution processed devices, respectively.
