Europium- and lithium-doped yttrium oxide nanocrystals that provide a linear emissive response with X-ray radiation exposure

Abstract

[Y_2−xO₃; Eu_x, Li_y] nanocrystals display scintillation responses that correlate linearly with incident radiation exposure at X-ray excitation energies ranging from 40–220 kVp, and thus can serve as sensing elements for next-generation radiation dosimeters designed for diagnostic and therapeutic applications.
