Resumen:
Optically stimulated luminescence (OSL) properties of K2YF5 crystals singly doped with different
concentrations of Tb3þions and doubly doped with Tb3þand Ce3þor Tb3þand Dy3þhave 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.% Tb3þ, have been studied. Finally, the OSL signal
peculiarities for K2YF5:1 at.% Tb3þhave been compared to those of a commercial Al2O3:C dosimeter.
