摘　　要：采用物理气相沉积方法制备了质量比为2∶1的Rubrene∶MoO3混合薄膜,研究了混合薄膜的光学性质和电学性质.结果表明:随着衬底温度的升高,混合薄膜的光学带隙变窄,说明MoO3诱导Rubrene产生中间能级,形成电荷转移复合物.随着衬底温度的升高,混合薄膜与金属电极形成欧姆接触,增强了混合薄膜的导电性.Rubrene:MoO3 mixed films with mass ratio of 2:1 were prepared by physical vapor deposition technology.The optical and electrical properties of the mixed films were studied.The results indicated that the energy band gap was narrowed with increasing substrate temperature which indicated that charge transfer complex(CTC)has formed.The contact of metal electrode with the mixed films was Ohmic contact when the substrate temperature was higher enough,thus the conductivity of the mixed films was enhanced.
