Description

Lithium magnesium phosphate (LiMgPO4, LMP) is a relatively new and very promising luminescent material that nowadays undergoes extensive studies. It has attracted huge attention of scientific society because it is characterized by a very high sensitivity to ionizing radiation, comparable or even higher than that of LiF:Mg,Ti (a commonly used standard material for TL radiation dosimetry) or Al2O3:C and BeO (the only materials commercially available for OSL measurements).

In this work, a review of results obtained over 7-years investigations of the LMP compound by the research group from IFJ PAN in Krakow will be presented. A crystal growth technology, luminescent properties investigations and possible new areas of applications will be discussed as well. Comparison of the LMP performance in different physical forms (powders and crystals) under the different modes of stimulation, as well as the application in various fields of radiation dosimetry, the efficiencies for different radiation qualities (photons, protons, alpha particles, neutrons) and the applications for real-time measurements will be the topics covered by this presentation. Presented results suggest that the LMP compound may be considered as promising material for applications in luminescent radiation dosimetry.
