ePoster: 

The pursuit of perovskite nanocrystals is a mandatory field dictated by the excellent optical properties demonstrated in these last years. The common colloidal approach to synthesize presents several limitation regarding the purification and their post-processing as thin layer. In this poster we review a different synthetic approach that leads to perovskite nanocrystals within a variety of porous matrices.   different  synthetic strategies imply the fine tuning of the microstructure of the matrix host : pore size distribution, the thickness and composition of the walls, the geometry of the void network and its topology. In addition, porous hosts provide the guest semiconductor with enhanced stability and versatility in terms of processing, which favors its integration in devices. A critical assessment of the optical quality of the hybrid perovskite nanomaterials so obtained, an analysis of the fundamental and applied aspects of the nanocrystal-matrix interaction, and a projected prospective of their impact in the fields of artificial lighting and renewable energy is provided.
