Data for: Toward Versatile Applications via Tuning Transition Wavelength of the WTa-SiO2 Based Spectrally Selective Absorber
Description
The file named "Reflectance and absorptance spectra" is the reflectance spectra and absorptance spectra of sample S1, S2, and S3 mentioned in the manuscript. The file named "Optical constant" is the refractive index and extinction coefficiency of materials, such as tungsten, silica, alumina, and WTa-SiO2 cermet layer. The file named "XRD spectra" is the X-ray diffraction spectra of single WTa-SiO2 cermet layer and the sample of S1, S2, and S3. The file named "Raman spectra" is the Raman spectra of the sample of S1, S2, and S3. The file named "Emittance spectra" is the measured and calculated thermal emittance of solar selective absorber S1, S2, and S3 at different temperatures. The file named "Efficiency" is the calculated photothermal efficiency of the solar selective absorber S1, S2, and S3.
