Abstract

An x-ray detector that is suitable for both imaging and dose rate measurement has a hybrid photoactive layer arranged between an electrode and a substrate. The hybrid photoactive layer includes a number of scintillators as well as a bulk heterojunction and is designed to produce indirect x-ray conversion. The bulk heterojunction absorbs the scintillator radiation to form electron-hole pairs that are detected electrically. The production takes place by a spraying process, in particular a co-spraying process of bulk heterojunction solution and scintillator particle suspension.
