EXAFS and EPR analysis of the local structure of Mndoped Li2B4O7
The local structure of Mn-doped Li2B4O7(001) was investigated using extendedX-ray absorption fine structure (EXAFS) at the Mn K edge and electron paramagnetic resonance (EPR). The location of the Mn dopant in a lithium tetraborate crystal is consistent with occupation of a site with strong oxygen coordination. The Mn–O bond lengths are similar to those observed with Mn doping of the icosahedral...

متن کاملFe(3+) ions in alkali lead tetraborate glasses--an electron paramagnetic resonance and optical study.
Glass systems of composition 90R(2)B(4)O(7)+9PbO+1Fe(2)O(3) (R=Li, Na and K) and 90Li(2)B(4)O(7)+(10-x)PbO+xFe(2)O(3) (x=0.5, 1, 3, 4, 5, 7 and 9 mol %) have been investigated by means of electron paramagnetic resonance (EPR) and optical absorption techniques. The EPR spectra exhibit three resonance signals at g approximately 6.0, 4.2 and 2.0. The resonances at g approximately 6.0 and 4.2 are a...
متن کاملShear Bond Strength of Porcelain Veneering to Nickel-Chromium, Chromium-Cobalt, Zirconia and Lithium Disilicate
Background and Aim: High chipping rates of the veneering porcelain in zirconia ce-ramic restorations have been reported in many clinical studies. However, information on the bonding behavior of veneering porcelain to zirconia and lithium disilicate frameworks is limited. The purpose of this study was to evaluate the bond-ing strength of porcelain veneering to zirconia, lithium disilicate, nicke...
متن کاملSynthesis of strontium borate doped with Pb by solid state method and characterization of its thermoluminescent glow curve
Strontium Tetraborate doped with Lead SrB4O7:Pb powder was prepared by solid state method. The formation of Strontium Tetraborate compound was analyzed by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). Thermoluminescence Glow Curve of gamma irradiated sample was investigated in order to use as a thermoluminescent dosimeter. Because of excellent mechanical properties, non-hygros...
