Nanoantennas: Single Bipyramid Plasmonic Antenna Orientation Determined by Direct Photoluminescence Pattern Imaging (Advanced Optical Materials 4/2013)




One-photon luminescence of single plasmonic nanoparticle is demonstrated by G. Lu, Q. Gong and co-workers to determine its 3D orientation using a direct emission pattern imaging technique. This is an efficient way, using macroscopically measurable optical signals, to explore a nanoscale structure nonperturbatively. The findings on page 335 show the technique's great potential for characterizing optical nanoantennas, for optical imaging and sensing in materials science and biological applications.
