N2 - Applications of commercially available, highly efficient inorganic scintillators (particle size: μm) are limited by their low solubilities in both polymeric and sol-gel matrices. On the other hand, organic scintillators, though highly soluble in polystyrene-based matrices, are not compatible with an efficient neutron inorganic absorber, 6Li, and their applications with 6Li as neutron scintillators are strictly limited. Here, preparation and surface modification of organic nanoparticles and inorganic nanocrystals are demonstrated as a means to increase dispersion and compatibility of scintillators with neutron-absorbing materials and matrices. A survey of nanoparticles, including PPO, POPOP-doped polystyrene nanoparticles, CdSe/ZnS core/shell quantum dots, Y2O3:Ce (5%), LaPO 4:Ce (10%), and 6Li3PO4 nanocrystals, in various matrices, along with their results in beta, alpha, or neutron detection is discussed.
