A neutron detector is disclosed. The neutron detector includes an optically transparent, low density solid porous matrix containing nanoparticles of a neutron absorbing material having a neutron absorption capture cross-section of at least about 70 barns, optionally doped with a scintillating material, for absorbing neutrons and emitting scintillation photons; and at least one detector element connected to the optically transparent neutron detector to detect fluorescence. |
