N2 - This article presents results of thermoluminescence (TL) and photoluminescence (PL) measurements performed on beta-irradiated K 2 YF 5:Tb 3+ +PTFE pellets. K 2 YF 5 crystals doped with 0.1% of trivalent optically active Tb 3+ ions in pellets form were investigated. The TL glow curve of K 2 YF 5:Tb 3+ +PTFE has a simple structure with two well-defined peaks centered at 170 and 307°C. The TL sensitivity of the K 2 YF 5:Tb 3+ +PTFE irradiated with beta radiation was found to be higher than that of commercial phosphor TLD-100 (LiF:Mg,Ti), at the same conditions of irradiation and readout. Moreover, PL measurements performed on the terbium doped material show the presence of Terbium as Tb 3+ in the material.
