Effects of Substrate Temperature on the Properties of Alq3 Amorphous Layers Prepared by Vacuum Deposition

In this study, various Alq3 amorphous layers are prepared by vacuum deposition at different substrate temperatures Tsub. The surface morphology, structural information, and electrical and optical properties of these as-deposited layers are studied by atomic force microscopy, X-ray diffraction, J–E curves, and photoluminescence studies, respectively. The optimum deposition conditions for Alq3 amorphous layers with respect to Tsub are also discussed.
