Photostimulated luminescence of Ba12F19Cl5 : Eu

Rey, J.M.
Published in Journal of Luminescence. 2002, vol. 97, no. 3-4, p. 224-228
Abstract The absorption and photostimulated spectra of single crystals of the new substance Ba12F19Cl5 doped with Europium ions were studied. Creation of color-center-type absorption bands was observed under C band UV irradiation of the doped crystals. These samples show photostimulated luminescence when subsequently excited with the 20,492 cm−1 line of an Ar ion laser. Our experiments support the assignment that the PSL signal is from the Eu2+ ions. This system may be of interest as an UV storage phosphor.
