The electret properties of disperse media based on LiF crystals with color centers

Thermally stimulated current spectroscopy and optical spectroscopy methods were used to study effect of gamma radiation on the electret properties of disperse media based on LiF crystal. The comparative data were obtained for the samples with the different structure of color centers, and also for the objects on the basis of a glass matrix. The obtained results indicate that the essential contribution in process of formation of considerable electret forces in studied environment, alongside with mechanical activation, can be brought by defects created by ionizing radiation.
