Linear-response nanocrystal scintillators and methods of using the same

摘要

Systems and devices incorporating radiation detection, and techniques and materials for improved radiation detection are provided that involve a nano-scintillator exhibiting a linear luminescent emission response to stimulating electromagnetic radiation. The nano-scintillator can include at least one nanocrystal comprising a rare earth element, a lanthanide dopant, and a spectator dopant, wherein the nanocrystal exhibits a linear luminescent emission response to stimulating electromagnetic radiation of wavelengths less than 100 nm. As one example, the nanocrystal is [Y2-x03; Eux, Liy], where x is 0.05 to 0.1 and y is 0.1 to 0.16, and has an average nanoparticle size of 40 to 70 nm. These nanocrystals can be fabricated through a glycine combustion method.
