Method for preparing metal halide nanocomposites

Abstract

The invention relates to a method for the preparation of luminescent nanocomposites comprising metal halide nanocrystals co-embedded with inorganic salts in the pores of a porous metal oxide matrix comprising the steps of: a) preparing a mixture comprising at least a metal halide, a combination of inorganic salts, and porous metal oxide particles in the absence of an organic solvent; b) heating above the melting temperature of the mixture of step a); c) cooling to obtain the nanocomposite. It further relates to nanocomposites obtained with the claimed method and optoelectronic devices, tracers and tagging material comprising the same.
