Abstract
A photonic antenna is an organized multi-component arrangement in which several chromophores absorb the incident light and channel the excitation energy to a common acceptor component. Numerous attempts to make such systems have been presented in the literature. We have developed photonic antennae based on a host-guest system which shows exciting properties. The host material is zeolite L, a hexagonal crystal with one-dimensional channels along the crystal axis. As guests we have used a wide range of highly fluorescent dye molecules which can enter the channels but do not interact electronically because of geometrical constraints. These systems are able to collect and transport excitation energy by radiationless energy transfer. Light shining on the cylinder is first absorbed and the energy is then transported by the dye molecules inside the tubes to a desired region. The principle of two types of photonic antenna materials is illustrated below:
