dc.description.abstract | Polycrystalline samples of new scheelite-type tungstates, Pb1 3x xPr2xWO4 with 0.0098 6 x 6 0.20, where denotes
cationic vacancies have been successfully prepared by a high-temperature solid-state reaction method using Pr2(WO4)3 and
PbWO4 as the starting reactants. The influence of the Pr3+ substitution in the scheelite framework on the structure and optical
properties of prepared new ceramic materials has been examined using powder X-ray diffraction method (XRD) and
UV-Vis-NIR spectroscopy. The results of dielectric studies of Pb1 3x xPr2xWO4 samples showed both low values of dielectric
constant (below 14) and loss tangent (below 0.2). The electrical conductivity and thermoelectric power measurements revealed
a low conductivity ( 2 × 109 S/m) and the sign change of thermoelectric power around the temperature of 366 K
suggesting the p-n transition. These results are discussed in the context of vacancy, acceptor and donor levels as well as
the Maxwell-Wagner model. | pl_PL |
