Hybrid-organic X-ray detector with conductive channels

A method for producing a detector for high-energy radiation, the method including:

• providing a substrate with a first electrical contact;
• forming and active layer directly or indirectly over the substrate and including an organic matrix of a photoactive material and non-soluble scintillator particles distributed homogeneously therein;
• forming a second electrical contact directly or indirectly over the active layer;
• wherein the active layer is formed with a mixing ratio between the scintillator particles and the organic matrix such that:
• (a) adjacent pairs of scintillator particles are spaced apart from each other by a maximum distance of five times a depth of penetration of radiation emitted by an individual scintillator particle;
• and
• (b) a cumulative thickness of the organic matrix between the two contacts is at least three times the depth of penetration of radiation emitted by an individual scintillator particle.

A detector for high-energy radiation, including:

• a substrate with a first electrical contact;
• an active layer including an organic matrix made of a photoactive material and non-soluble scintillator particles essentially distributed homogeneously therein, and
• a second electrical contact,
• wherein the scintillator particles are spaced apart from each other by areas of the organic matrix, and
• wherein a mixing ratio between the scintillator particles and the organic matrix in the active layer is selected such that adjacent pairs of scintillator particles are spaced apart from each other by a maximum distance of five times a depth of penetration of radiation emitted by an individual scintillator particle;
• and
• wherein a total mass of the scintillator particles is at least 8 times greater than a total mass of the organic matrix.
