Parametric Studies on Artificial Morpho Butterfly Wing Scales for Optical Device Applications

Figure 6

Reflectance curves of Morpho structures for two different materials ((a) SiO₂ and (b) GaP) with varying surrounding indices (from 1.0 to 1.1 with 0.02 steps), (c) CIE plots of reflectance spectra for Morpho structures with four different materials (i.e., SiO₂, , ZnS, and GaP). Arrows indicate directions for surround index increment.
