摘要: Abstract Optical properties of tantalum pentoxide thin films have been investigated. The were prepared by the sol-gel method using spin coating process. Refractive index and absorption coefficient calculated with respect to spinning velocity number layers from optical transmission measurement in range 200-1100 nm. Forbidden bandgaps are found be 3.75 ± 0.12 eV independent film thickness rate.
