Abstract
New hybrid Poly (vinyl) alcohol (PVA)‐InTiO transparent thin film was prepared by dip‐coating method. Characteristic of MO vibrations (InO and TiO) were confirmed from Fourier transform infrared spectroscopy. The X‐ray diffraction patterns revealed that the mixed phases of rutile TiO2 and cubic In2O3 were present in the hybrid film. Scanning electron microscopy images showed spherical shape mixed In2O3 and TiO2 nano particles embedded in the polymer matrix. The presence of elements such as In, Ti, and O are confirmed from energy dispersive X‐ray spectroscopy. High transmittance (80%) and wide band gap energy (4.1 to 3.75 eV) values were observed from optical study. High dielectric constant (18 to 23) and low dielectric loss values were obtained from dielectric study. The observed amorphous nature, enhanced optical, and dielectric properties indicated that the hybrid thin film could be used as high‐к layer in transparent thin film transistor and in opto‐electronic device applications in near future.
