description

The photoluminescence (PL) of Mn-doped LiBaF3 shows a weak Mn2+ emission band at 710 nm; the corresponding excitation bands are between 210 and 620 nm. After X-irradiation the PL spectrum shows two new bands peaking at 600 and 670 nm that are tentatively assigned to perturbed Mn2+ emissions; the intensity of all PL bands is increased. Magnetic circular dichroism (MCD) and the MCD-detected electron paramagnetic resonance (EPR) measurements show that F-type centres are formed after X-irradiation. The EPR measurements indicate that there is a spatial correlation between the F-type centre and the Mn2+ dopant. (© 2005 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
