TLDR
In this article, a large improvement in solid-state lighting emission was achieved by coupling emitters with very high intrinsic quantum efficiency (QE) to collective plasmonic resonances in periodic arrays of aluminum nanoantennas.Abstract:
Light sources based on reliable and energy-efficient light-emitting diodes (LEDs) are instrumental in the development of solid-state lighting (SSL). Most research efforts in SSL have focused on improving both the intrinsic quantum efficiency (QE) and the stability of light emitters. For this reason, it is broadly accepted that with the advent of highly efficient (QE close to 1) and stable emitters, the fundamentalresearchphaseofSSLiscomingtoanend.Inthisstudy,wedemonstrateaverylargeimprovementinSSLemission(above 70-fold directional enhancement for p-polarized emission and 60-fold enhancement for unpolarized emission) using nanophotonic structures. This is attained by coupling emitters with very high QE to collective plasmonic resonances in periodic arrays of aluminum nanoantennas.OurresultsopenanewpathforfundamentalandappliedresearchinSSLinwhichplasmonicnanostructuresareableto mold the spectral and angular distribution of the emission with unprecedented precision.
