“…Therefore it is reasonable to conclude that the 4.7 eV emission band is connected to the STE having the Cl À 2 core. The above mentioned weak emission band at 2.4 eV is similar to bands seen in BaFCl, BaFBr and in BaFCl 1Àx Br x mixed crystals spectra and most probably this band is connected with oxygen impurity [9,13].…”

PACS 71.35.Aa, 78.55.HxThe creation and relaxation of electronic excitations in pure crystalline SrFCl and Sm 2þ doped SrFCl were investigated using vacuum ultraviolet (VUV) spectroscopic methods. In the emission spectra of pure SrFCl and SrFCl : Sm 2þ a strong emission band in the vicinity of 4.7 eV was detected, connected to self-trapped exciton (STE) having a Cl À 2 core. The threshold for creation of STE was detected at 8.5 eV in the excitation spectrum of pure SrFCl and at 7.6 eV for Sm 2þ doped SrFCl. It was demonstrated that the excitation spectrum of Sm 2þ emission is determined with direct excitation of a Sm 2þ center below 7.6 eV and with excitation of the SrFCl host above 7.6 eV.

“…The independence is further supported by a considerably different PL lifetime for the 470 nm emission than for the Eu 2þ emission (Hesse et al, 2009) (not displayed). These observations along with the above chemical considerations strongly suggest the interpretation that the 470 nm emission band is related to O 2À -ions incorporated into the BaFBr:Eu lattice which was suspected earlier by Dong et al (1995) and Radzhabov and Otroshok (1995). The observation, that the F-center absorption measurements indicate a higher F-center concentration (Fig.…”

“…The following possibilities may account for this. (1) the absorption of O 2À F centers locate at $4.9 eV [9] , and the concentration of these centers declines after UV light irradiation, which shades the absorption of H(F 2 À ) centers, (2) O 2À ions substitute at F À sites, which results in the decrease of H(F 2 À ) centers. An O F 2À center changes into an O F À center after bonding a hole.…”
