Abstract

Abstract: The goals of this work are to determine the luminescence properties of KYF4 single crystals doped with different concentrations of Ce 3+ ions and to evaluate their possible application as a detector of beta radiation. In particular, thermoluminiscence, radioluminiscence and optically stimulated luminescence properties of KYF4 : Ce 3+ exposed to beta radiation have been studied and very good dosimetric properties have been obtained within the dose range 0.02–20 Gy. Highlights: RL, TL and OSL properties of KYF4 doped with Ce have been investigated for the first time. KYF4 doped at 0.2 at.% Ce concentration shows the highest TL and OSL response. Very good linearity and no fading are observed in the dose range from 0.01 up to 100 Gy. KYF4:Ce (3 at.%) yields maximum RL intensity and a good repeatability. Results show that KYF4:Ce is promising to be used in radiation dosimetry.
