Abstract

A series of phosphors with composition La _9.33-x-y-zSi ₆O ₂₄O ₂ (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 Ce ³ enhances 1.53 μm emission of Er ³ by a factor of 50, while the effect of Yb ³ is to quench the luminescence.
