NOT KNOWN FACTS ABOUT BAGA4SE7 CRYSTAL

′�?, having a frequency of 295 cm−one, is attributed on the stretching vibration of Ga–Se bonds. The two-phonon absorption with the 295 cm−1 phonon corresponds to the crystal IR absorption edge, as an alternative to the residual absorption peak. Density useful theory computations demonstrate the residual absorption from the BGSe crystal o
