Abstract
The creation and relaxation of electronic excitations in pure crystalline SrFCl and Sm2+ doped SrFCl were investigated using vacuum ultraviolet (VUV) spectroscopic methods. In the emission spectra of pure SrFCl and SrFCl: Sm2+ a strong emission band in the vicinity of 4.7 eV was detected, connected to self-trapped exciton (STE) having a Cl-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 Sm2+ doped SrFCI. It was demonstrated that the excitation spectrum of Sm2+ emission is determined with direct excitation of a Sm2+ center below 7.6 eV and with excitation of the SrFCl host above 7.6 eV.
