N2 - In the present study, ZnO and TiO2 nanofillers with different concentrations are integrated into the PMMA matrix on the glass substrate using a cost-effective spin coating technique. XRD investigations show the maximum crystalline complexity of 24.56% crystallinity with a rise in filler concentration up to x = 10 wt%. SEM and EDS studies signify the homogenous distribution and compatibility of nanofillers in the host PMMA matrix. Raman spectroscopy demonstrates the influential transition peak identified at 840 cm−1 for an optimized filler concentration of x = 10wt%. The C=O and C–O of host PMMA are out of plane bending with an estimated PED of 64ηC=O + 16ηC–O, indicating a pivotal role in filler and matrix complex formulation. Optical studies show enhancement in transmittance with a rise in filler concentration up to 10 wt%, offering a maximum value of nearly 85%. The course also emphasizes the solid antireflection nature with a decreased bandgap value to 1.94 eV. The observed upsurge in optical conductivity suggests the number of free charges present in the nanocomposite films. The increase in optical conductivity with a reduced energy bandgap of these PMMA/(15 − x) ZnO (x)TiO2 shows a promising contender for optical device applications.
