Directional plasmonic nanoantennas to enhance the purcell effect

We will present plasmonic nanoantennas, composed of silver nanocubes strongly coupled to gold films, which are the optical and infrared (IR) frequency counterparts to the well-established patch antennas used in microwave frequencies for mobile communications. These nanoantennas are ideal platforms to boost several photodynamic processes, such as spontaneous emission. Interestingly, they can be built based on bottom-up chemical synthesis approaches and their radiation spectrum can be easily controlled.
