Fig. 5From: Spatial localization of hotspots in Fano-resonant plasmonic oligomers for surface-enhanced coherent anti-Stokes Raman scatteringSimulated NFE and SECARS maps computed at a plane 1 nm above the top surface of the quadrumer for the Raman band of adenine (740 cm-1). a-c and e-g NFE plots at CARS (738 nm), pump (780 nm) and Stokes (828 nm) wavelengths; d and h the corresponding SECARS maps; In the plots (a)-(d), all the dimensions are along Fig. 1a. In h the white dotted circles show the nano disksBack to article page
