Nanoparticles of transparent semiconducting zinc silicon oxide, with diameter below 4 nm, were found to exhibit a variety of electron affinity ranging from 3.6 eV to 2.7 eV, by altering Si content. Resulting nanoparticles can be dispersed in glycol solvents, showing a good surface flatness in the spin-coated films.
