A series of luminescent rare-earth ion-doped hexagonal II-type Gd oxycarbonate phosphors Gd2-xRExO2CO3 (RE = Eu(3+), Yb(3+), Dy(3+)) have been successfully synthesized by thermal decomposition of the corresponding mixed oxalates. The Yb(3+) doped Gd-oxycarbonate has evidenced a high persistent luminescence in the NIR region, that is independent from the temperature and makes this materials particular attractive as optical probes for bioimaging.
一系列发光的稀土离子掺杂的六方 II 型 Gd 氧碳酸盐荧光粉 Gd2-xRExO2CO3（RE=Eu(3+)、Yb(3+)、Dy(3+)）已通过相应混合草酸盐的热分解成功合成。Yb(3+)掺杂的 Gd-氧碳酸盐在近红外区域表现出高的持久发光，该发光与温度无关，这使得该材料作为生物成像的光学探针具有特殊的吸引力。
