摘要：
The influence of excess surfactant concentration on the uniformity and self-assembly of dip-coated FePt nanoparticle films on thermally oxidized Si substrates is reported. The nanoparticle solution in non-polar solvents contains excess surfactant, which is varied in a range from 10(-6) to 10(-1) parts by volume. Uniform, homogeneous films of nanoparticles are obtained only in a narrow range of excess surfactant concentration of about 10(-3) parts by volume. (C) 2003 Elsevier B.V. All rights reserved.
