New large size luminescent nanoparticles have been prepared, based on lead bromide or iodide organic perovskites. The luminescent center is made of PbX42- octahedrons. The preparation of the nanoparticles stems from fast nebulization and subsequent lyophilization of perovskite DMF solutions. The particles described have an average size of 60 nm, but a 20-500 nm range is in principle accessible. These new nanoparticles constitute an alternative to Q-dots which allows variable size while retaining the same emission wavelength, like silica particles functionalized with organic dyes, but with a higher stability under illumination.
