Abstract: A stabilized quantum dot composite includes a plurality of luminescent semiconducting nanoparticles embedded in a matrix comprising an ionic metal oxide. A method of making a stabilized quantum dot composite includes forming a mixture comprising a plurality of luminescent semiconducting nanoparticles dispersed in an aqueous solution comprising an ionic metal oxide. The mixture is dried to form a stabilized quantum dot composite comprising the plurality of luminescent semiconducting nanoparticles embedded in a matrix comprising the ionic metal oxide.
