CuO thin films were spray-deposited onto a glass substrate and the deposition temperature was varied from 450 to 550 ℃ with 25 ℃ steps. The 450 ℃ deposition temperature was found to be the optimum condition for crystal growth. However, the FESEM images revealed that the grain size increases with raising the deposition temperature. To […]
AbstractEffects of low-intensity UV treatment on the optical constants of red BS dye-doped polymethyl methacrylate (PMMA) film including refractive index, extinction coefficient, real and imaginary parts of dielectric constant, band gap energy, Urbach energy, and refractive index dispersion parameters are measured and calculated. Changes in optical constants mainly occurred in the UV–VIS range. Red BS […]
