BaP6 N10 NH:Eu2+ as a Case Study-An Imidonitridophosphate Showing Luminescence.

ABSTRACT: Barium imidonitridophosphate BaP6 N10 NH was synthesized at 5?GPa and 1000?°C with a high-pressure high-temperature approach using the multianvil technique. Ba(N3 )2 , P3 N5 and NH4 Cl were used as starting materials, applying a combination of azide and mineralizer routes. The structure elucidation of BaP6 N10 NH (P63 , a=7.5633(11), c=8.512(2)?Å, Z=2) was performed by a combination of transmission electron microscopy and single-crystal diffraction with microfocused synchrotron radiation. Phase purity was verified by Rietveld refinement. 1 H and 31 P solid-state NMR and FTIR spectroscopy are consistent with the structure model. The chemical composition was confirmed by energy-dispersive X-ray spectroscopy and CHNS analyses. Eu2+ -doped samples of BaP6 N10 NH show blue emission upon excitation with UV to blue light (?em =460?nm, fwhm=2423?cm-1 ) representing unprecedented Eu2+ -luminescence of an imidonitride.
