Abstract
Disclosed is a method for preparing a hybrid organic/inorganic composition including inorganic nanoparticles functionalized by at least one molecule chosen from photoluminescent charged organic molecules, the method including bringing into contact, in a single-phase solvent medium, at least one photoluminescent charged organic molecule and non-swelling phyllosilicate nanoparticles having a thickness of 1 nm to 100 nm, and a larger dimension of 10 nm to 10 μm. Also disclosed are hybrid photoluminescent nanoparticles compositions obtained by this method.
