Single crystals of $R{\mathrm{Mg}}_{2}{\mathrm{Cu}}_{9}$ ($R=\mathrm{Y}$, Ce-Nd, Gd-Dy, Yb) were grown using a high-temperature solution growth technique and were characterized by measurements of room-temperature x-ray diffraction, temperature-depend

This paper presents the results of a simulation study of extrinsic defects in lead tungstate crystal. The results reveal that monovalent ions preferentially enter the Pb sites, whereas pentavalent ions preferentially occupy the W sites, and both of t

Heavily trivalent ions doped into PbWO4 will exert a distinct influence on the scintillation performance and the conductivity of the crystal. In the light of the doping mechanism, the microstructure of the heavily La3+ doped and undoped PbWO4 crystal

Under the [010] electron diffraction (ED), the 002 superstructure spot was observed and tentatively ascribed to the ordering of [2(La3+ Pb)• - V″ pb] dipolar clusters. A superstructure model was proposed in light of the ED and HRTEM image. Rietve

A lead tungstate crystal, with 1% mol La3+ doping, was grown by the Czochralski method and its structure determined by single-crystal X-ray diffraction techniques. It retains the scheelite-type structure with cell constants a=b=5.4587(6) A, c=12.038(

The phase regions around quasicrystals and approximants (QC/ACs) are rich pools for electron-poor intermetallics with novel, complex structures, and bonding patterns. The present SrAu(4.30(1))In(1.70(1)) (1) and CaAg(3.54(1))In(1.88(1)) (2) were synt
