Abstract:
1. A neutron detector comprising: a substrate having an upper substrate surface; a sensor disposed on the upper substrate surface, the sensor including a first electrode and a second electrode disposed parallel to the upper substrate surface, and an active material layer sandwiched between the first and second electrodes; and a neutron capture layer disposed on the substrate and contacting the sensor, said neutron capture layer including a neutron capture material for capturing thermal neutrons directed onto the neutron detector and for converting each said captured thermal neutron into a charged particle, wherein the active material layer comprises a donor material and an acceptor material operably formulated and arranged to convert said charged particles into electron-hole pairs, and to separate and transport the electrons-holes to the first and second electrodes, wherein at least one of the donor material and the acceptor material comprises nanoparticles, and wherein the first electrode is disposed directly on the upper substrate surface such that the sensor is disposed between at least a portion of the neutron capture layer and the substrate.
