摘要：

In this work, a broad investigation on the optical parameters of TPD:Alq3 composite thin films is reported. The films are prepared from different solution-processed mixtures and are deposited onto the quartz substrate in order to measure their optical response with UV?Vis?NIR spectrophotometer. Results showed that the nondispersive refractive index and dielectric constant of TPD was increased from 1.49 to 1.75 and from 2.19 to 2.99 by Alq3 doping, respectively. The optical conductivity of TPD:Alq3 (1:3) composite was seen to be highly improved, reaching the value of 144 S/cm. The Wemple and DiDomenico (WD) model was used to find the band gap (EWD g ) of the films and results were compared to those deduced from the Tauc?s equation (Eoptg ). It was found that the investigated films obey the single-oscillator model in defining the strength of the optical transitions.
