In the FNR approach based on conventional scintillation screen, blurry and poor resolution imaging is obtained due to the light scattering of grain boundary or bi-phase interface. The alternative FNR strategy is based on single-component high-transparent scintillation screen (BTPP)1.8(HTPP)0.2MnBr4, which is composed of randomly arranged high-steric-hindrance cations (BTPP+, HTPP+) and luminous unit [MnBr4]2−. The fast neutrons carrying the internal information of the tested object, interact with H atom in the organic cation BTPP+, HTPP+ to generate recoil protons. The recoil protons deposit energy on the luminous unit [MnBr4]2− and induce the generation of electron hole pairs, stimulating visible fluorescence, and then the fluorescence information is received by charge-coupled device (CCD). Distinct and high-resolution imaging is obtained, thanks to the transparency of the scintillation screen reducing light scattering.
