Abstract

Scientists often find in nature the inspiration to solve their problems and challenges. As a matter of fact, photosynthesis, where solar radiation is harvested efficiently and converted into chemical energy, is an appealing bioprocess. Therefore, in the herein re-ported work we intend to mimic a therein ongoing process, and develop materials which en-able a broadband light absorption, whereas displays mainly red-edge emission. These lumi-nescent materials were designed by means of the selection of suitable organic dyes and their subsequent allocation into unidimensional pores of L-type zeolite. Such confinement boosts the energy transfer, being this a key process for energy transport and conversion. As consequence, the herein customized nanomaterial allows efficient light harvesting over a wide spectral region (antenna behavior) and, thanks to the ongoing energy transfer, fluo-rescence at the red edge is mainly recorded, with potential applications in many (bio)tech-nological areas.
