Crystal structures and luminescence properties of Li6MN4:Ce3+ (M = Mo, W)
Abstract
<jats:title>Abstract</jats:title><jats:p>The compounds Li<jats:sub>6</jats:sub>MoN<jats:sub>4</jats:sub> and Li<jats:sub>6</jats:sub>WN<jats:sub>4</jats:sub> were prepared from the reactants <jats:italic>M</jats:italic> (<jats:italic>M</jats:italic> = Mo, W) and Li<jats:sub>3</jats:sub>N in a radiofrequency furnace at 1000 °C. The lithonitridometallates crystallize in the tetragonal system with the lattice parameters: <jats:italic>a</jats:italic> = 6.6844(1), <jats:italic>c</jats:italic> = 4.9294(1) Å for Li<jats:sub>6</jats:sub>WN<jats:sub>4</jats:sub> based on single-crystal X-ray diffraction data and <jats:italic>a</jats:italic> = 6.6611(3), <jats:italic>c</jats:italic> = 4.9338(3) Å for Li<jats:sub>6</jats:sub>MoN<jats:sub>4</jats:sub> taken from powder X-ray diffraction data. Colorless to slightly reddish single-crystals of the tungsten compound were isolated and the crystal structure was refined in the space group <jats:italic>P</jats:italic>4<jats:sub>2</jats:sub>/<jats:italic>nmc</jats:italic> (no. 137) with <jats:italic>Z</jats:italic> = 2 and the powder X-ray data of the molybdenum compound were analyzed by a Rietveld refinement. Both structures belong to the Li<jats:sub>6</jats:sub>[ZnO<jats:sub>4</jats:sub>] type published by Hoppe et al. in 1987 (Untenecker H., Hoppe R. <jats:italic>Z. Anorg. Allg. Chem.</jats:italic> 1987, <jats:italic>551</jats:italic>, 147–150) and could be doped with Ce<jats:sup>3+</jats:sup> for the first time. The investigated compounds show a reddish color impression upon UV to blue irradiation and exhibit a broad emission band with a maximum at <jats:italic>λ</jats:italic><jats:sub>max</jats:sub> = 693 nm (fwhm 97 nm) for Li<jats:sub>6</jats:sub>MoN<jats:sub>4</jats:sub> and at <jats:italic>λ</jats:italic><jats:sub>max</jats:sub> = 653 nm (fwhm 133 nm) for Li<jats:sub>6</jats:sub>WN<jats:sub>4</jats:sub>.</jats:p>
