It is demonstrated that detailed informations on the atomic arrangement of colloidal metal particles can be obtained by high-resolution electron microscopy (HREM) combined with appropriate techniques to prepare ultrafine powders.
ChemInform Abstract
It is demonstrated that detailed informations on the atomic arrangement of colloidal metal particles can be obtained by high-resolution electron microscopy (HREM) combined with appropriate techniques to prepare ultrafine powders. HREM-imaging of a Ag particle of 35 Å diameter shows that discrete Ag atoms are located around a decahedral center. The Au colloids contain either deca- and icosahedral, multiply twinned particles of 100-400 Å size, or triangular particles of 200 Å up to more than 1000 Å.
