| Abstract: | Hydroxyl free zinc oxide nanorods have been synthesized by a catalyst free surfactant based one-step solid state reaction
process. The powder X-ray diffraction studies reveal well defined wurtzite peaks due to crystalline ZnO, while optical absorption
spectra represent prominent exciton absorption and remarkable blueshift in the onset of absorption. As predicted by transmission
electron microscopy, the ZnO nanorods are ∼100 nm long and of ∼20 nm dia. Further, luminescence aspects of such nanorods are
studied for possible deployment in optoelectronics devices.
