A combination of nanohole array and gold nanoparticles (Au NPs) was fabricated on the c‐Si substrate. The substrate is then optically characterised through reflectance spectra. Reduction in reflectance around 68.91% was observed in the wavelength range of 300–1100 nm for the hybrid nanostructured surface. The reduction in reflectance is attributed to a gradual change in refractive index owing to the nanohole array and the localised surface plasmon resonance of the Au NPs.
