- With the increase of Mg doping amount, the absorption edge in ultraviolet-visible absorption spectra of Mg:Mn:LiNbO_3 crystal shifts to the violet and then inversely to the red when Mg doping concentration is up to the threshold. 晶体的紫外-可见吸收光谱表明,当掺镁量没有达到阈值浓度时,Mg:Mn:LiNbO_3晶体的吸收边随掺镁量的增大发生紫移,当掺镁量达到阈值浓度后,晶体的基础吸收边又发生相对红移。
- Doping Cr2O3 increase resistivity of ATO Doping ZnO reduce resistivity of ATO. After doping three oxide the transparency of ATO film is all reduced. Effect of oxide on transparency of ATO films followed the sequence Cr2O3> Fe2O3> ZnO. 结果表明;Cr2O3增大ATO纳米粉末晶粒尺寸;对ATO粉体电阻率急剧增加;搀杂ZnO增加ATO纳米粉末晶粒尺寸;但降低ATO粉末的电阻率;搀杂Fe2O3能大大减少ATO纳米粉末晶粒长大;当Fe2O3搀杂量超过一定值时使电阻率急剧上升;3种氧化物均降低ATO薄膜的透射率;其程度为Cr2O3>Fe2O3>ZnO.
