Abstract

The TL, XL, PTTL and OSL of BaFCl:Eu²⁺ and SrFCl:Eu²⁺ were studied. The PTTL stimulation spectra of BaFCl:Eu⁺ had maxima at the Eu³⁺, Eu²⁺ absorption bands and at the long wavelength tail of F absorption. The PTTL appeared at the same temperatures and with the same thermal activation energies as the TL peaks, indicating that the same defects are responsible for the trapping states. The TL emission spectra of the BaFCl:Eu²⁺ crystals showed narrow bands at 315 and 365 nm and a broader band near 435 nm. The OSL and XL showed the same bands as well a 385 nm emission. The 365 nm band also appeared in SrFCl:Eu² and is attributed to the emission of Eu²⁺.
