Abstract

Deposition parameters and optical constants n and k have been determined for A1-N-F and A1-O-F dielectric films which have a refractive index n~1.4 and a low k prepared in D.C. magnetron sputtering system. A new solar selective surface of graded Al-N and A1 base layer with A1-N-F antireflection film has been fabricated, and good agreement is obtained between computed and experimentally measured reflectances and absorptances for the surface incorporating A1-N-F, solar absorptance increases to~0.97(AD) and ~.0.95(HT). The solar selective surface have been analyzed by Auger and ESCA.
