Abstract
An organic x-ray detector and a method of making the organic x-ray detector are disclosed. The x-ray detector includes a TFT array disposed on a substrate, an organic photodiode layer disposed on the TFT array, a barrier layer disposed on the photodiode layer, and a scintillator layer disposed on the barrier layer, such that the barrier layer includes at least one inorganic material.
Claims18
An organic x-ray detector, comprising:
- a TFT array disposed on a substrate;
- an organic photodiode layer disposed on the TFT array;
- a first electrode disposed in between the TFT array and the organic photodiode layer;
- a barrier layer disposed on the organic photodiode layer, wherein the barrier layer comprises at least one inorganic material;
