X-ray diffraction and Mössbauer effect are measured for Fe1-xTix alloys produced by vapor quenching. The amorphous phase is realized 0.2 < x 0.75, while the single b.c.c. phases of α-Fe-type β-Ti-type > 0.8, respectively. average value quadrupole splitting isomer shift gradually vary with increase in x, they discontinuously change at boundaries about = confirming results measurements. Fe1-xTix-Legierungen, aus der Dampfphase hergestellt, werden mittels Röntgenbeugung und Mößbauereffekt...

Abstract Undoped and Tb-doped Ba 3 Gd(PO 4 ) single crystals were synthesized by the floating zone method. Photoluminescence (PL), scintillation, thermally stimulated luminescence (TSL) properties of obtained evaluated. The highest PL quantum yield value was from 5% crystal. In X-ray-induced scintillation TSL spectra, undoped sample represented an emission peak originating 4f–4f transition Gd 3+ at 310 nm. samples peaks transitions Tb in range 310–620 dose response functions, 1% showed...
