RESEARCH ON SPECTRALLY SELECTIVE MATERIALS AND SURFACES
Abstract
Research on spectrally selective materials an surfaces with particular reference to their application to solar collection and thermionic conversion is discussed. The three phases of the studies were: the use of spectrally selective surfaces as solar absorbers; the use of spectrally selective surfaces in thermionic diodes; and the radiative characteristics of phosphor materials. In the first phase, test specimens of metallic oxides on metal substrates were prepared and subjected to thermal equilibrium measurements in a solar test facility. In the second phase, theoretical studies of nickel oxide were made, and experimental measurements of its absorption spectrum and thermionic emission properties were accomplished. The third phase discusses the radiative properties of phosphor materials and reports the measurement of the fluorescence spectrum of a rare earth chelate. (Author)
