Caught on film: A semitransparent and intensely luminescent monolayer film of oriented Gd(2)O(3):0.05 Eu platelet crystallites is fabricated by annealing the precursor hydroxide film (see scheme). The photoluminescence properties of the as-transformed film are greatly improved over those of the hydroxide film, and are much more pronounced than those of the corresponding Gd(2)O(3):0.05 Eu powder.

通过对前驱体氢氧化物薄膜进行退火处理，制备出了由取向的Gd₂O₃:0.05 Eu片状微晶组成的半透明且强烈发光的单层薄膜（见图例）。转化后的薄膜的光致发光性能相较于氢氧化物薄膜有了极大提升，且比相应的Gd₂O₃:0.05 Eu粉末更为显著。
