复合薄膜
探讨了镍掺杂量、煅烧温度对薄膜结构和形貌的影响.通过X射线衍射、红外光谱、扫描电子显微镜等测试手段对Ni/SnO
2
复合膜的结构和形貌进行表征.结果显示
500 ℃ 下煅烧的薄膜样品的结晶度较高
粒径小
颗粒分布均匀.用紫外-可见分光光度计和四探针电阻仪对其进行光学、电学性能测试
结果显示:适量的Ni掺杂可以提高SnO

薄膜在近紫外光区的吸收
Ni/SnO
2
薄膜在近紫外光区的吸收随着Ni
2+
掺杂摩尔分数从5%增加到10%而逐渐减小.当Ni
2+

复合薄膜的导电性能最好.
Ni/SnO
2
films were prepared by spin coating Ni/SnO
2
gel on the glass substrates. The effects of the doping amount of nickel and calcination temperature on the structure and morphology of Ni/SnO
2
films were discussed. The structure and morphology of Ni/SnO
2
composite film were characterized by using XRD
IR
SEM and other testing methods. The results show that the particles of the film calcined at 500 ℃ have high crystallization
small size
and distribute uniformly. The right amount of Ni
2+
doping can improve the absorbance in the near ultraviolet region of SnO
2
film
and the absorbance in the near ultraviolet region of Ni/SnO
2
film decreases with the increasing of Ni
2+
mole fraction from 5% to 10%. The conductivity of Ni/SnO
2
film is the best when Ni
2+
mole fraction is 6%.
