The co-doping of Fe and PO4 constructs a stable oxygen-packed framework, which can alleviate lattice distortion, reduce the mixing of cations and increase the reversible reaction of 2O/(O2), contributing to outstanding structural stability. The synergetic strategy of anion and cation and the co...
. In Ca6Ba(PO4)4O, the average cation-oxygen bond lengths in the two tetrahedra are 1.534(13) and 1.529(15) Å, while bond angles range from 105.1(8) to 112.9(7)° and 105.3(7) to 112.8(9)°, with bond valence sums of 5.0(1) for both P atoms. In Ca6Ba(PO4)4O:0.5%Mn...
The recent developments achieved in improvement of the electrochemical performances of LiFe 1- y Mn y PO 4 -based materials are summarized, including selecting the synthetic methods, nanostructuring, surface coating, optimizing Fe/Mn ratios and particle morphologies, cation/anion doping, and rational ...
In this work, instead of more common cation-substitution approach, we investigated the luminescence properties of Eu2+ and Mn2+ co-doped halophosphate solid solution Ca5(PO4)3(F0.8Cl0.2) via anion substitution synthesized by high temperature solid state reaction method. The formation of the ...
Pieczkaite is isostructural with apatite, Mn is the dominant cation at both the [9]- and [7]-coordinated-cation sites in the structure, and Cl is the dominant monovalent anion.doi:10.2138/am-2015-5117TaitDepartmentKimberlyDepartmentBall
In this work, instead of more common cation-substitution approach, we investigated the luminescence properties of Eu^(2+) and Mn^(2+) co-doped halophosphate solid solution Ca_5(PO_4)_3(F_(0.8)Cl_(0.2)) via anion substitution synthesized by high temperature solid state rea...
The general formula of manitobaite is Na_(16)□)(Mn~(2+),Fe~(2+),Mg,Zn,Ca)_(25)(Al,Fe~(3+))_8(PO_4)_(30), and the end-member formula is (Na_(16)□)Mn~(2+)_(25)Al_8(PO_4)_(30). There are 80 cation sites and 120 anion sites in the structure. There are 30...
