ATOMIC-FORCE MICROSCOPY USED FOR THE CHARACTERIZATION OF PRECIPITATEDCOLLOIDAL PARTICLES

Colloidal particles play an important role in advanced materials scien ce since their size, shape and structure can be controlled and influen ced in a wide range. These parameters can be determined by atomic forc e microscopy. In this work, photographic AgBr microcrystals as well as amorphous nanoceramics consisting of TiO2, FeYO3 or Fe2O3 particles w ere studied and characterized on different imaging scales. Surface fin e structures on the silver halide microcrystals as well as the amorpho us-crystalline transition of the oxide particles will be discussed.
