摘要：

The luminescence of Ag+ in SrB4O7 in the crystalline and glassy modification is reported. Three types of Ag centres are identified. The luminescence of isolated Ag+ ions in the crystalline phase is characterized by a relatively long emission wavelength (290 nm), a small Stokes shift (6200 cm-1) and a short decay time (14 mus at 300 K). Also luminescent Ag+-pairs and non-luminescent Ag0 are observed. In the glassy modification of SrB4O7 the same Ag centres are observed. The emission bands are shifted to longer wavelengths.
