Abstract
Small particle compositions including nanoparticle compositions are provided. The particle compositions, in some cases, are characterized by having an extremely small average particle size (e.g., 150 nanometers or less). The small particles may comprise a semiconductor material and/or a light-emitting material. In some embodiments, the particles may be in the form a preferred shape including platelets, amongst others. The small particle compositions may be produced in a milling process. In some embodiments, the milling process uses preferred types of grinding media to form milled particles having desired characteristics (e.g., particle size, shape). The small (or nano) particle compositions may be used in a variety of different applications including light-emitting applications. In certain applications, it may be desirable to form thin films from the small particle compositions.
