Crystal structures and luminescence properties of Ca 3 RE 2 Si 4 O 8 Makoto Kobayashi, Takuya Yasunaga, Chikako Nagahama, Kotaro Fujii, Masatomo Yashima, Minoru Osada, Hideki Kato, Masato Kakihana
New oxynitrides, Ca 3 RE 2 Si 4 O 8 N 4 ( RE = Y, La, Ce), contain rare isolated 12-membered Si(O,N) 4 ring units and four distinct cation sites. Ce 3+ -activated samples exhibit composition-dependent luminescence from deep blue to bluish green.
