Zinc oxide (ZnO) thin film is grown on glass substrate by the sol-gel spin coating technique. The prepared film annealed at 450 °C. X-ray diffraction shows that the ZnO Film is polycrystalline with (002) preferential orientation. We have found the Surface roughness was minimum (12.4 nm) by atomic force microscopy. The optical band gap is found to be 3.12±0.01 eV by UV-visible Spectroscopy. The Wave...
In the present study styrene acrylonitrile based polymeric waveguides have been optimized with the help of aging (variation of baking time keeping the temperature constant), annealing (variation of baking temperature keeping the time constant), concentration and thickness (physical). Propagation losses are lowest at an annealing temperature of 100 o C and aging time of 8h. The values of effective...
