Abstract

A single crystal of Ba0.9Ce0.1LuAl0.2Si3.8N6.9O0.1(barium cerium lutetium aluminosilicate nitride oxide) was obtained by heating a mixed powder of Ba3N2, Si3N4, Al, Lu2O3, and CeO2at 2173 K for 1 h under N2gas at 0.85 MPa. X-ray single-crystal structure analysis revealed that the title oxynitride is hexagonal (lattice constants:a= 6.0378 (5) Å,c= 9.8133 (9) Å; space group:P63mc) and isostructural with BaYbSi4N7. (Ba,Ce) and Lu atoms occupy twelvefold and sixfold coordination sites, respectively.
