Abstract: Solar energy absorptive coatings that comprise single cermet layers with a homogeneous metal volume fraction exhibit an absorptance of about 0.8, which is not high enough for practical solar applications. To achieve absorptance greater than 0.9, graded composite films have been developed, but they give rise to higher thermal emittance due to the absorption edge not being sharp enough. This leads to increased thermal emittance at high operating temperatures, in the range of 300.degree. C. to 500.degree. C. There is now disclosed a novel solar selective surface coating which is composed of two cermet layers, with different metal volume fractions in each layer. The two cermet layers have different thicknesses, and the layers have thicknesses and volume fractions such that solar radiation is absorbed by internal absorbing and phase cancellation interference, but the cermet layers are substantially transparent in the thermal infrared region.

The added particles may be very small and serve only to refine the precipitating intermetallics in the alloy or they may be larger and serve as reinforcing particles in a composite with the alloy. The products obtained are also novel.

Abstract: A recording layer 3 including shape-memory alloy thin films 311, 312 and a hydrogen storage alloy thin film 32, a dielectric thin film 4, and a reflective thin film 5 are stacked on a surface of a substrate 2 in the described order. Irradiation of recording light causes the hydrogen storage alloy thin film 32 to release hydrogen gas and contract in volume at the same time, creating a space 321 in the film. The shape-memory alloy thin films 311, 312 are deformed by the gas pressure in space 321, allowing space 321 to enlarge its thickness. Upon exposure to erasing light, shape-memory alloy thin films 311, 312 tend to restore their shape prior to deformation, applying pressure to the hydrogen gas in space 321 so that the hydrogen gas is occluded again and space 321 is substantially extinguished. Reversible release and occlusion of hydrogen gas enables to rewrite the recording information.
