Electron Paramagnetic Resonance and Xhyphen;Ray Studies in Doped Silver Carbonate

摘要

For Y(III)hyphen; or Gd(III)hyphen;doped silver carbonate with the ratio of dopant toAg, nthinsp;ge;thinsp;0.005, a new orthorhombic crystal structure is reported withathinsp;equals;thinsp;13.94 Aring;, bthinsp;equals;thinsp;5.97 Aring;, andcthinsp;equals;thinsp;5.30 Aring;, determined from xhyphen;ray studies. Electron paramagnetic resonance investigations onggr;hyphen;irradiated Y(III)hyphen;doped silver carbonate also indicate the presence of a new crystal structure. The same new crystal structure is thermally attained in undoped carbonate at sim;150deg;C under 3 atm of CO2.
