摘要：

In this report, a systematic study of mixed polymorph and binary integration of MoO3 multilayer structures has been given. The spin-coated multilayer nanorods (hexagonal and orthorhombic) of MoO3 are fabricatedon glass substrates and TiO2 coated glass substrate at different temperatures, i.e., 300 degrees C and 500 degrees C. The microstructure and surface analysis of the deposited films were characterized by X-ray diffraction (XRD), Raman spectroscopy, and scanning electron microscopy (SEM). The optical properties of the films were characterized by UV-visible absorption spectrophotoscopy and theoretical analysis of the transmittance data. The optical bandgap falls between the wavelength range from 225 nm to 310 nm. Due to the optical bandgap in UV region and good transmission properties in the visible region, the fabricated thin-film structures may be developed as selective wavelength optical filters, which can control the unwanted distribution of UV radiation.
