Abstract
- In this work, we introduce an indirect X‐ray detector with organic photodiode (OPD). OPD, as a photodetector, is attractive due to its easy fabrication of even large area or flexible form factor. The top electrode of OPD is fabricated with a translucent organic‐metal‐organic (OMO) structure to absorb more light energy by the surface plasmonic effect at the organic‐metal interface. In addition, the new fabricated OPD has a microcavity effect, which is generated between the top and bottom electrodes, makes the broad absorption spectrum of CuPc (active layer) narrower, and tune to the narrow Gd2O2S scintillator emission wavelength. Through X‐ray experiments, the microcavity effect was shown to be useful and controllable by varying the thickness of C60 in the bulk heterojunction (BHJ) structure of the active layers which are composed of C60 and CuPc.
