Abstract :In present study, Graphene oxide doped Perylene-3,4,9,10-tetracarboxylic dianhydride based organic nanocomposites prepared for various mass ratio insert ignore into journalissuearticles values(m GO /m perylene = 0.005, 0.01, 0.03 and 0.1); by the sol-gel process. The graphene oxide was synthesized by modified Hummers method. The prepared organic nanocomposite samples were characterized by SEM, EDX, FTIR and Optical spectroscopy techniques. Typical scanning electron microscopy insert ignore into journalissuearticles values(SEM); images indicate the presence of particles with different sizes from 432 to 841 nm. The optical band gap of the samples were determined from the diffused reflectance spectra and Eg values for undoped and graphene oxide doped insert ignore into journalissuearticles values(0.005, 0.01, 0.03 and 0.1); Perylene organic nanocomposite were found to be 2.43, 2.68, 2.55, 2.57 and 2.68 eV, respectively. This results evaluated that Graphene oxide doped Perylene based organic nanosemiconductors can be producted by sol-gel techniques and this materials can be used for advanced technological applications
