Two optical functions realized in a single MoOCl₂ nanostructure. (IMAGE)
Caption
The left panel shows an electron micrograph of MoOCl₂ nanodisks arranged on a substrate, and the lower-left schematic shows the device structure consisting of a MoOCl₂ nanodisk on an Au reflective film and a glass substrate. The graph on the right shows the reflectance spectra measured for two light-polarization directions. Depending on the polarization of incident light, the same nanostructure can switch between a light-concentrating resonance and a light-trapping resonance.
