Incorporation of trivalent cations in synthetic garnets [A.sub.3][B.sub.5][O.sub.12] (A=Y, Lu-La, B=Al, Fe, Ga)

Article Abstract:

Static-lattice atomistic calculations were used to study the solution energy for the incorporation of trivalent cations at 3 different lattice positions of 12 synthetic garnets. It was found that the incorporation of trivalent ions on substitutional sites does not require any charge-compensating defects, mainly driven by ionic size differences and the energy difference between the preferred substitution site and the next favored site was relatively small in several cases and hence foreign ions could be inserted at two different positions.

Synthesis and spectroscopy of lanthanide ion-doped Y2O3

Article Abstract:

Investigation is done to compare the high-resolution luminescence properties of Y2O3:Eu(super 3+) powders synthesized by three different methods. The particles are more uniformly shaped and filled when prepared by the FSP method than by CSP.
