摘要：

A series of phosphors with composition La9.33-x-y-zSi6O24O2 (x=Er, y=Ce, z=Yb) with the silicate oxyapatite structure were synthesized by a sol-gel spin-coating technique. The products formed as well-crystallized laminae 6-8 nm thick. Spectroscopic measurements in the near-infrared showed that excitation through Ce3+ enhances 1.53 mu m emission of Er3+ by a factor of 50, while the effect of Yb3+ is to quench the luminescence.
