Modifying photoisomerization efficiency by metallic nanostructures.


Trans-to-cis photoisomerization efficiency of azobenzene dye is artificially modified from 0.09 to 0.38 when dye molecules are placed close to gold nanoparticle films with different structures. Transient fluorescence and surface enhanced Raman scattering measurement verify that the enhancement and reduction of photoisomerization efficiency come from the… (More)
