ZnO nanoparticles in the form of quantum dots (QDs) have been dispersed in SiO 2 matrix using StÖber method to form ZnO QDs-SiO 2 nanocomposites. Addition of tetraethyl orthosilicate (TEOS) to an ethanolic solution of ZnO nanoparticles produces random dispersion. On the other hand, addition of ZnO nanoparticles to an already hydrolyzed ethanolic TEOS solution results in a chain-like...
