镝 - 引用次数：14
It was shown from the experiment that the Nd (Dy, La) -doping reduces the transmissivity of SnO_2 films by ultraviolet-visible spectrophotometer test (350-900nm). As Nd doping concentration increase, the optical bandgap drops (2.62-3.07ev).
经稀土镝(钕、镧)掺杂后,SnO_2薄膜的光透射率(入射波长300-900nm内)均有不同程度的降低。
