Abstract
Optically stimulated luminescence (OSL) properties of K2YF5 crystals singly doped with different concentrations of Tb3+ ions and doubly doped with Tb3+ and Ce3+ or Tb3+ and Dy3+ have been investigated for the first time. Radioluminescence spectra and OSL efficiency for stimulation with different wavelengths of light have been analyzed for each compound. Also, dosimetric characteristics of the most efficient composition, namely K2YF5:1 at.% Tb3+, have been studied. Finally, the OSL signal peculiarities for K2YF5:1 at.% Tb3+ have been compared to those of a commercial Al2O3:C dosimeter.
