摘要
Rare-earth related optical emission in oxide semiconductors is strongly influenced by the local co-ordination around the rare-earth centres. In this contribution, we examine the effect of aluminium co-doping on the local fine structure of neodymium-doped titanium dioxide (TiO2:Nd, TiO2:Nd-Al) thin films with single-phase anatase structure, via luminescence and X-ray absorption fine structure (XAFS) measurements. Increasing the concentration of Al in these materials leads to the co-ordination around Nd3+ ions being distorted, which in turn leads to an enhanced photoluminescence (PL) intensity. We explain this in terms of a distortion of the nearest neighbour oxygen bonds with Nd3+.
