The current–voltage (I–V), micro-Raman and various optical properties of 4-hydroxy coumarin Schottky diode were studied. From its optical study, the optical band gap (Eg), transport band gap, binding energy and Urbach energy were found to be around 3.5 eV, 3.72 eV, 0.28 eV and 327 meV respectively. The given compound was following an indirect allowed transition. Photoluminescence of the current compound shows a various emission bands in UV region. From micro-Raman study, different modes related with the current structure were obtained and discussed. Some basic techniques related with device were carried out to find out different diode parameters. The observed properties shown by this molecule indicates its possible application for modern organic devices.
