Treść
Three different methods - melt quenching (MQ), twin rollers (TR) and mechanosynthesis (MS) - were used for the preparation of the 15Ag2O·70V2O5bullet operator15P2O5 glass - a good amorphous semiconductor. It was demonstrated that physical properties of the final material depend to some extent on the preparation method. As-received samples were characterized by: X-ray diffractometry (XRD), differential scanning calorimetry (DSC), Raman scattering, X-PDF method and impedance spectroscopy (IS) in a wide temperature range from -80 to 230°C. Main conclusion of these studies is, that substantially different synthesis routes can be used to produce glasses of almost identical thermal and structural properties but different electronic conductivity. The explanation of the origin of that difference was proposed and discussed.
