OPTICAL AND LUMINESCENT PROPERTIES OF CaF2 CRYSTALS IRRADIATED WITH 14 MeV ENERGY

The paper studies color centers in synthetic calcium fluoride crystals, which arise from irradiation with 14 MeV electrons at room temperature.The irradiated samples also measured the kinetics of phosphorescence decay and thermoluminescence.The concentration of the formed color centers was calculated using the Smakula-Dexter ratio.It was found that the phosphorescence of the irradiated calcium fluoride crystal lasts up to ~7 days.The thermoluminescence curves show four peaks.

Abstract

The paper studies color centers in synthetic calcium fluoride crystals, which arise from irradiation with 14 MeV electrons at room temperature.The irradiated samples also measured the kinetics of phosphorescence decay and thermoluminescence.The concentration of the formed color centers was calculated using the Smakula-Dexter ratio.It was found that the phosphorescence of the irradiated calcium fluoride crystal lasts up to ~7 days.The thermoluminescence curves show four peaks.
