Influence of Polymodal Radiation Processes on Thermoluminescence and Its Quenching in MgO:Mn2+ Crystals
This comprehensive study relates to the most radiation‐sensitive peaks (450 and 550 K) of high‐temperature (300–775 K) thermally stimulated luminescence (TSL) of MgO:Mn2+ crystals, with impurity content of 77, 155, and 285 ppm, irradiated with fast electrons. For a more complete and clearer picture of the nonmonotonic (polymodal) radiation processes stimulated in doped crystals, the results of a study of a group of nominally pure crystals irradiated under the same experimental conditions are also considered. Based on the correlation of the dose dependences of the studied characteristics, the mechanisms of TSL peaks formation are established. Despite a much lower concentration than divalent manganese ions, ferric ions cause significant changes in thermoluminescence and its quenching in irradiated MgO:Mn2+ crystals.
期刊介绍：
physica status solidi is devoted to the thorough peer review and the rapid publication of new and important results in all fields of solid state and materials physics, from basic science to applications and devices. Being among the largest and most important international publications, the pss journals publish review articles, letters and original work as well as special issues and conference contributions.
physica status solidi b – basic solid state physics is devoted to topics such as theoretical and experimental investigations of the atomistic and electronic structure of solids in general, phase transitions, electronic and optical properties of low-dimensional, nano-scale, strongly correlated, or disordered systems, superconductivity, magnetism, ferroelectricity etc.
