Qısa məlumat

The structure of undoped and europium-doped ZnGa 2Se 4 has been studied, and the interplanar spacings, the Miller indices of the observed reflections, and their relative intensities have been determined. The photoluminescence spectra of ZnGa 2Se 4 and ZnGa 2Se 4:Eu 2+ crystals have been measured at temperatures from 77 to 230 K. The 566-nm band in the spectrum of ZnGa 2Se 4:Eu 2+ is assigned to the Eu 2+4f 65d→4f 7( 8 S 7/2) electronic transition, and the bands at 591 and 646 nm are attributed to transitions of donor-acceptor pairs. © 2010 Pleiades Publishing, Ltd.
