OSL properties of KMgF:Tm for dosimetric applications as OSL dosimeter.

The optically stimulated luminescence (OSL) properties of undoped and Tm-doped KMgF fluoroperovskite have been investigated for the first time. KMgF compounds were synthesized by solid state reaction method and two different procedures were employed to improve the contact among the reagents, namely, the compressed powder was put either in an alumina crucible or in a platinum foil. The maximum OSL emission was found in samples prepared in an alumina crucible and doped with 0.
