采用碳热还原氮化法制备了稀土碳氮化物Y2 Sι4N6C和Y2 Sι4N6C：M3+(M=Ce，Tb)。以Ho2Si4N6C的原子坐标为起始模型，用Rietveld精化方法确定了Y2 Sι4N6C的晶体结构。晶格结构为Ho2 Sι4N6C单斜晶系[P21/c，a=5.9295(1)，b=9.8957(1)，c=11.8800(2)A，β=11.8800(4)°，Z=4]。在详细结构分析的基础上，对掺杂材料Y2Si4N6C：Ce3+和Y2Si4N6C：Tb3+的光致发光性能进行了表征。
Rare-earth silicon carbonitrides, Y 2 Sι 4 N 6 C and Y 2 Sι 4 N 6 C:M 3+ (M = Ce,Tb), were prepared by a carbothermal reduction and nitridation method. The crystal structure of Y 2 Sι 4 N 6 C was determined by Rietveld refinement using the atomic coordinates of Ho 2 Si 4 N 6 C as a starting model. The host lattice was isostructural with Ho 2 Sι 4 N 6 C of monoclinic system [P2 1 /c, a = 5.9295(1), b= 9.8957(1), c = 11.8800(2) A, β = 119.63(4)°, and Z = 4]. The photoluminescence properties of doped materials, Y 2 Si 4 N 6 C:Ce 3+ and Y 2 Si 4 N 6 C:Tb 3+ , were characterized on the basis of the detailed structural analysis result.
