LiF with different dopants has been one of the most investigated materials to use as thermoluminescent dosimeter. 115, Lomas del Campestre, 37150 Leon, Guanajuato (Mexico) A., E-mail: [Centro de Investigaciones en Optica, A. 103, Lomas del Campestre, 37150 Leon, Guanajuato (Mexico) Diaz T, L. [Universidad de Guanajuato, Division de Ciencias e Ingenierias, Loma del Bosque No. Synthesis and characterization of europium doped LiF phosphorĮnergy Technology Data Exchange (ETDEWEB) A similar relation was found to be unsatisfactory in the case of LiF. The true stress-strain rate data for CaF2 and LiF- 22 CaF2 could be represented by a power-law relation with the strain rate sensitivities lying between 0.05 and 0.2 for both materials. The true stress-strain curves for the single crystals were found to exhibit three stages in an intermediate range of temperatures and strain rates, whereas those for the eutectic showed negative work-hardening rates after a maximum stress. The deformation behavior of CaF2 and LiF single crystals compressed in the 111 and the 100 line directions, respectively, are compared with the mechanical properties of polycrystalline LiF- 22 ( mol pct) CaF2 eutectic mixture in the temperature range 300 to 1275 K for strain rates varying between 7 x 10 to the -7th and 0.2/s.
