摘要：

The relationship between the surface microstructure and the optical properties of solar absorbing electrodeposited black chrome films has been studied by scanning electron microscopy (SEM), X-ray photoemission spectroscopy (XPS) and sputter depth-profiling techniques. The black chrome films have been determined to consist of a top layer of small (≈400 Å) Cr2O3 particles with one or two sublayers of larger (≈1000 Å) closely packed chromium particles. The optical properties of the solar absorping films have been measured and analyzed via the spheroid model and it has been shown that the optical response of the particulate black chrome films is significantly determined by their microstructure. © 1979.
