Influence of geometric design parameters, such as the washer width d, gap width g, outer washer radius, and material composition on the transmission, reflectivity, and absorbance have been investigated. The results show that increasing d results in a red shift in the transmission spectrum and enhances resonant coupling, while decreasing g reduces the optical coupling and shifts the spectrum toward shorter wavelengths. The full width at half-maximum (FWHM) and the quality factor are also highly dependent on the washer radius and structural length, highlighting the trade-off between the transmission efficiency and resonance resolution. The proposed filter achieves a transmittance exceeding 70%, a transmittance bandwidth of 10 nm, and a quality factor of up to 70. Furthermore, the comparison of silver and gold using the Drude model showed that silver offers higher transmission efficiency and better quality factor compared to gold, making it an ideal choice in high-performance optical filtering applications.

The resulting glasses were characterized using various analytical techniques. X‑ray diffraction (XRD) confirmed the amorphous nature of samples containing up to 6 mol% CrCl3, as evidenced by a broad diffraction halo between 20 and 30°. At higher CrCl3 concentrations, partial crystallinity was observed. Fourier-transform infrared (FTIR) spectroscopy indicated a gradual increase in bridging oxygen content, suggesting enhanced polymerization within the phosphate network. Substituting Na2O with CrCl3 led to an increase in the density, molar volume, and packing density, accompanied by a reduction in the free volume. UV-visible spectroscopy revealed two prominent absorption bands near 470 and 650 nm, attributed to Cr3+ ions in distorted octahedral coordination. A weak band near 300 nm, associated with Cr6+ ions, was detected only in samples with lower CrCl3 concentrations. The optical band gap decreased from 3.5 to 2.8 eV (indirect transition) and from 4.04 to 3.0 eV (direct transition), while the refractive index increased from 2.214 to 2.371 with CrCl3 addition up to 9 mol%.
