The luminescent characteristics of RE (RE 3+ =Eu, Tb, Dy, Sm and Tm)-doped K 2 GdZr(PO 4 ) 3 have been investigated. The band in the range of 130–157nm in the VUV excitation spectra of these compounds is attributed to the host lattice or PO 43− group absorption and the band from 157nm to 215nm with the maximum at 188nm is due to the O–Zr charge transfer...
A nickel diphosphate with mixed cations, Na(NH 4 )[Ni 3 (P 2 O 7 ) 2 (H 2 O) 2 ] with a layered structure has been synthesized under hydrothermal conditions for the first time and characterized by single crystal X-ray diffraction, IR spectroscope and magnetization measurements. The structure consists of cis- and trans-edge sharing NiO 6 ...
