There are several methods to synthesize specks, each tailored to achieve specific sizes, shapes, and compositions. Common methods include:
1. Chemical Vapor Deposition (CVD): This technique involves the chemical reaction of vapor-phase precursors to form solid specks on a substrate. 2. Sol-Gel Process: A wet chemical technique that produces specks through the transition of a solution system from a colloidal suspension to a gel phase. 3. Ball Milling: A mechanical method that involves grinding bulk material into nanoscale particles.
