Using a Mach-Zehnder interferometric system, we examined the refractive indices, birefringence, and opto-mechanical behavior of blank PP, PP/TiO₂, and PP/ZnO nanocomposite fibers under various conditions, including different polarization orientations and during cold drawing processes. The 2D Fourier transform algorithm is employed to analyze interferometric data, enabling precise measurements of refractive index profiles and birefringence. Results show that both TiO₂ and ZnO nanoparticles significantly enhance the optical and mechanical properties of PP fibers. PP/TiO₂ fibers exhibited the highest refractive index (1.530) and birefringence (0.0459), followed by PP/ZnO (1.522 and 0.040) and blank PP (1.520 and 0.031). The maximum draw ratios achieved were 4.2, 3.9, and 3.5 for PP/TiO₂, PP/ZnO, and blank PP fibers, respectively, indicating improved mechanical properties in the nanocomposites. Antimicrobial efficacy was evaluated using the shaking flask method and optical density measurements against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans.

The pH levels were used to modulate the luminescent of CMO:Tb. To confirm the potential application of proposed phosphors, Blueberry anthocyanin (BBA) was loading onto CMO:Tb surface to form a luminescence probe. The synthesized phosphors and probes were characterized using X-ray diffraction (XRD), FT-IR spectra, transmission electron microscopy (TEM), and high-resolution TEM (HRTEM). As a proof-of-concept, the constructed probes were adopted to evaluate the acidity of solution. The results showed that luminescence emission intensity at 546 nm increased with pH value increasing in the range of 2–12. Meanwhile, the color of the sensor solution changed from bright red to pink, then to purple, and finally to yellow as the pH varies between 2 and 12.

In addition, in the synthesized material, the cubic phase byproduct CeO₂ was found due to the highly oxidizing nature of the cerium element. This occurred due to 6 min microwave irradiation because the microwave-assisted technique offered random distribution of heating during the supply of 800-W power for 30 s, followed by 12 cycles. Additionally, the presence of Fe₂O₃ was also confirmed through Match software-assisted Rietveld refinement analysis through phase matching.
