Abstract:
The optical reflectances of evaporated deposits of gold on aluminum have been measured in the visible and IR regions. Aggregation of the gold and diffusion of the aluminum into the gold by heat treatment produces surfaces with high absorptance in the visible and high reflectance in the infrared, characteristics required of selective solar absorbers. The effects of prolonged heating at 350 degrees C are shown to be slight.
