摘要: ABSTRACTThe nanocomposite films of poly vinylpyrrolidone (PVP) with different amounts viz., 2, 4, 6 and 8 wt% cesium aluminate (CsAlO2) have been fabricated using solvent casting technique. The effect nanofiller content on the optical properties PVP/CsAlO2 has established by UV-visible spectroscopy. transmittance studies revealed that UV light absorbing nature considerable visible transparency. Fourier Transform Infrared (FTIR) spectral visualizes CsAlO2 structural behaviors PVP, while reveals an obvious change in electronic band structure leading to a significant reduction gaps. scanning electron microscopic (SEM) establish morphological changes PVP matrix upon doping CsAlO2. measured refractive index (RI) depends volume fraction result indicates substantial increase RI ...
