Optical emission near a high-impedance mirror.

摘要: Solid state light emitters rely on metallic contacts with a high sheet-conductivity for effective charge injection. Unfortunately, such also support surface plasmon polariton and lossy wave excitations that dissipate optical energy into the metal limit external quantum efficiency. Here, inspired by concept of radio-frequency high-impedance surfaces their use in conformal antennas we illustrate how electrodes can be nanopatterned to simultaneously provide DC electrical conductivity at frequencies. Such do not SPPs across visible spectrum greatly suppress dissipative losses while facilitating desirable Lambertian emission profile. We verify this studying enhancement photoluminescence lifetime dye emitter layer deposited electrodes.
