Proton-conducting composite membranes derived from poly(2,6-dimethyl-1, 4-phenylene oxide) doped with phosphosilicate gels

Solid State Ionics, 2006
Abstract Proton-conducting composite membranes were prepared by doping phosphosilicate gels into SPPO polymer matrix. The structure of gels was examined by 31 P MAS-NMR. The composite membranes were characterized in terms of TGA, mechanical property, water uptake and conductivity. It was found that the composite membranes were thermally stable up to

Radiation-induced luminescence and photoluminescence from sol–gel silica glasses and phosphosilicate glasses by 1MeV H+ irradiations

Physica B: Condensed Matter, 2004
Abstract Radiation-induced luminescence (RIL), photoluminescence (PL) and PL excitation (PLE) spectra have been applied to the study of photon emission from sol–gel silica glasses and phosphosilicate glasses. The photoemissions from oxygen excess-related defects are observed at about 1.98 eV by PL and RIL.
