“…7 shows the energy of 4.1 70.15 eV reported for the CT-band of Nd 3 þ in Ref. [22]. Since the endpoint of the arrow is at the Nd 2 þ ground state, it confirms our assignment that the 295 nm band in Fig.…”

“…7), E V ¼ À5.34 eV is obtained. Next, one needs the exciton creation energy E ex in SrI 2 which is well established from different sources [12,[20][21][22]. We use 5.5 eV (225 nm) that applies to an exciton creation at about 10 K, as indicated with arrow 2 in Fig.…”

“…31 In SrI 2 crystal having close band gap energy the alike emission was also ascribed to self-trapped exciton emission. 3,4 The STE luminescence quenching with Eu 2+ concentration is due to the exciton emission and 4f-5d Eu 2+ absorption spectra overlapping. This fact makes possible a resonant transfer from exciton to Eu 2+ ions.…”

“…1 This material has been more extensively studied with optical spectroscopy methods within the past decade. Spectroscopic data measured in ultraviolet and vacuum ultraviolet (VUV) together with Ab Initio calculations provided the information about exciton and band gap energies [2][3][4][5] and is necessary for understanding mechanism of defect formation and their role in energy transfer.…”
