(a) Transmittance spectra of \(\alpha -{{\rm{MoO}}}_{3}\) thin film at seven different concentrations from 0.5% to 3.5%. b) Transmittance spectra of \(\beta -{{\rm{MoO}}}_{3}\) thin film at different concentrations from 0.5% to 3.5%, The thickness and the Ag – NPs radius was set at 100 nm and 5 nm, respectively. The respective labels are shown in the figure.
