To obtain left-circularly polarized (LCP) and right-circularly polarized (RCP) light, a linear polarizer and a quarter-wave plate are inserted in the light path. The scattered light from the sample passes by way of an goal lens (×60; numerical aperture, zero.70) and is guided to the charge-coupled device camera and the spectrometer. The…[Читать далее]

The collected spectra from the pattern are corrected by first subtracting the background from darkish present and then normalizing to the white reference. To demonstrate the chiroptical response of the plasmonic samples, the distinction between the scattering spectra measured with incident RCP and LCP light (denoted as IRCP − ILCP) is used4…[Читать далее]
