Title : Plasmonic arrays to tailor the emission 

By: Assistant Professor Shunsuke Murai, Department of Material Chemistry, Graduate School of Engineering, Kyoto University

When the metallic nanoparticles are arranged periodically in the scale of optical wavelengths, localized surface plasmon resonances excited on each nanoparticle can be coupled through diffraction.  This collective plasmonic mode is spatially extended in the plane of the array, whereas localized surface plasmon is a local effect bound in the particle.  In the talk, properties of the collective plasmonic mode are discussed with special emphasis on its application to emission modification.  When the array is placed on the phosphor layer, the emission profile of the layer changes drastically.  Several experimental data with different emission centers are given, to demonstrate the power of the array to shape the emission both spatially and spectrally. I will also show our recent works on non-plasmonic (Si) arrays.
