This allowed us to purposefully search for cheap, efficient, high-speed nanocomposite scintillators for the detection of neutrons, charged particles and low-energy gamma quanta. Nanoparticles of fluorides, oxides, polystyrene were synthesized and their surface was functionalized to ensure compatibility with the polymer matrix; polymeric scintillators loaded with inorganic particles were obtained; the sizes of nanoparticles and their distribution were determined; structural, phase and luminescent-kinetic studies of the obtained nanoparticles and nanocomposites were performed; the scintillation efficiency using gamma, X-rays and neutrons was determined; the models of scintillation process in nanoscintillators and nanocomposites accounting dimensional effects are proposed.
