Abstract
For this study thin films of 9,10-dibromoanthracene (DiBrAn) were prepared by hot wall evaporation technique onto the glass substrate under different experimental conditions for light emitting applications. These films were systematically characterized for structural, optical and electrical studies by x-ray diffraction, atomic force microscope, scanning electron microscope, Fourier transform infrared spectroscopy, UV-Vis spectroscopy, and photoluminescence investigations. On examination, crystallinity, electrical conductivity and optical band gap of the DiBrAn films were found to increase with increase in substrate temperature. The wide optical band gap and strong blue emission of DiBrAn make this material an efficient blue emitter.
