在用传统固相反应制备的CuRxY1-xO2(R=Eu，Tb或Tm)和CuRxCayY1-x-yO2中，晶格常数与组成的关系表明在Y3+位掺杂了Tb3+，Eu3+和Tm3+离子。在CuRxCay Y1-x-yO2和CuRxY1-xO2中，观察到了由Eu3+，Tb3+和Tm3+的f-f跃迁引起的明显的尖峰发射线。CuRx Cay Y1-x-yO2的P型电导率随钙离子浓度的增加而增大，表明在Y3+位掺杂了钙离子受体阳离子导致空穴浓度增加。这些结果表明，Eu、Tb或Tm稀土阳离子和Y~(3+)位上的Ca受体阳离子共掺杂可以控制钙钛矿型CuYO2氧化物的发光和电导。(2006 Wiley-VCH Verlag GmbH&Co.KGaA，Weinheim)
In delafossite‐type oxides of CuRx Y1–x O2 (R = Eu, Tb or Tm) and CuRx Cay Y1–x –y O2 prepared through the conventional solid state reactions, the lattice constant dependence on the composition implies doping with the Tb3+, Eu3+ and Tm3+ cations on the Y3+ site. Noticeable sharp emission lines due to the f–f transitions of Eu3+, Tb3+ and Tm3+ are observed at room temperature in CuRx Cay Y1–x –y O2 as well as CuRx Y1–x O2. P‐type conductivity of CuRx Cay Y1–x –y O2 increases with increasing Ca concentration, indicating the increase of hole concentration caused by doping with Ca2+ acceptor cation on the Y3+ site. These results indicate the controllability of the luminescence and conductivity in delafossite‐type CuYO2 oxides by co‐doping with Eu, Tb or Tm rare‐earth cation and Ca acceptor cation on the Y3+ sites.
