One of these complexes shows a fluorescence efficiency of 55% and prolonged photo-stability once entrapped in silica, demonstrating high potential for applications in energy conversion.RSC advancesTurning weak emitters into outstanding luminescent materials using rigid host media.PMC9048981EP/P015395/1BB/R013942/1Cucinotta FSani UTungulin DBizzarri CfalseTurning weak emitters into outstanding luminescent materials using rigid host media.The incorporation into rigid silica host structures leads successfully to a significant luminescence enhancement of two zinc(ii) dipyrrins, known to be weak emitters in solution.
