Synthesis of CaNbO with a Rynersonite-like Structure: Morphology, Rietveld Refinement, Optical, and Vibrational Properties.

In this study, we report the easy and low-cost synthesis of calcium niobate (CaNbO) with the isomorphic structure of the Rynersonite mineral for CaTaO. The samples were prepared by the ball milling method at room temperature at a synthesis time of 0.5, 1, 2, 3, and 4 h.

Rietveld Refinement, Morphology, and Optical and Photoluminescence Properties of a β-AgCuMoO Solid Solution.

Corner-truncated cubic β-AgCuMoO microcrystals were synthesized using the hydrothermal method. These were investigated by X-ray diffraction, confirming obtention of the spinel structure 3̅. Through Raman spectroscopy are confirmed all modes for the point group of .
