Abstract: Methods for preparing ferroelectric nanoparticles, liquid crystal compositions containing the ferroelectric nanoparticles, and electronic devices utilizing the ferroelectric nanoparticles are described. The methods of preparing the ferroelectric nanoparticles may include size-reducing a starting material comprising particles of a bulk intrinsically nonferroelectric glass to form glass nanoparticles having an average size of less than 20 nm, the glass nanoparticles comprising ferroelectric nanoparticles. Exemplary bulk intrinsically nonferroelectric glasses may include borosilicate glasses, tellurite glasses, bismuthate glasses, gallate glasses, and mixtures thereof, for example. The size reduction may be accomplished using ball milling with a solvent combination such as n-heptane and oleic acid. Liquid crystal compositions may include the ferroelectric nanoparticles in combination with a liquid crystal.
