Abstract:

Mossbauer spectroscopy is uesd to study the photostimulated luminescence material BaFBr:Eu for the first time. The results from Mossbauer study support the conclusion obtained from luminescence studies, that is in BaFBr:Eu, the ltalnescence effect of Eu~(2+) is much higher than that of Eu~(3+), Eu~(2+) lundnescence Anght be enhanced by Eu~(3+). Meanwhile, Mossbauer study may also provide useful information on the interaction of phonon on luminescence centers. All thoes results are helPful to the understanding of luminescence process.

Key words: BaFBr:Eu, Eu2+ and Eu3+, Photostimulated luminescence, Mossbauer spectrum, Emission spectrum
