Transition-Metal Phosphate Colloidal Spheres

摘要

Colloidal spheres are frequently studied in materials science. chemistry, and biologybecause their intrinsic properties can be tuned by changing parameters such as diameter, chemical composition, bulk structure, and crystallinity. To date, colloidal spheres have been widely used as fundamental building blocks in the fabrication of materials such as photonic bandgap (PBG) crystals (or photonic crystals),two-dimensional crystalline arrays for masks in lithography, and three-dimensional macroporous materials.The most-studied and best-established examples of such colloidal materials are silica and polymer colloids.
