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

and co-workers to determine its 3D orientation using a direct emission pattern imaging technique. This is an effi cient way, using macroscopically measurable optical signals, to explore a nanoscale structure nonperturbatively. The fi ndings on page 335 show the technique’s great potential for characterizing optical nanoantennas, for optical imaging and sensing in materials science and biological applications. NANOANTENNAS
