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.

Bismuth Oxide Nanoparticles Partially Substituted with Eu, Mn, and Si: Structural, Spectroscopic, and Optical Findings.

Interest in nanostructured partially substituted bismuth oxides has been increasing over the last years. Research on new synthesis methods, properties, and possible uses for these oxides is needed. The objective of this paper is to synthesize β-BiO, β-BiO:Eu, β-BiO:Mn, BiBiO, BiBiO/Li, BiMnO, and BiSiO nanoparticles and to investigate their structural, spectroscopic, and optical changes.
