Overview

Experimental study demonstrates tunable optical bandgap and dielectric properties in methyl cellulose films via green-synthesized zinc oxide, suggesting utility in sustainable photonics.

Key Points

  • To evaluate the structural, optical, and dielectric modulation of methyl cellulose films loaded with green-synthesized zinc oxide nanoparticles.
  • Synthesized zinc oxide (ZnO) nanoparticles via a tea-mediated green route calcined at 500°C.
  • Fabricated methyl cellulose (MC) nanocomposite films via solution casting with ZnO loading concentrations of 0, 4, 8, and 12 wt%.
  • Characterized structural, morphological, and optical behavior using FTIR, XRD, FE-SEM/EDX, and UV–vis spectroscopy alongside Tauc, absorbance spectrum fitting, and Wemple–DiDomenico models.
  • FTIR and XRD confirmed phase-pure wurtzite ZnO dispersion and strong interfacial hydrogen bonding via shifts in O–H and C–O–C vibration bands.
  • Increasing ZnO concentration caused a redshift in the absorption edge, progressively lowered the optical bandgap, and increased Urbach energy.
  • Wemple–DiDomenico dispersion analysis revealed enhanced refractive index dispersion and electronic polarizability with higher nanoparticle loading.
