Hardening and Optimizing of the Black Gold Thin Film as the Absorption Layer for Infrared Detector
Abstract: This paper reports on the study of the black gold thin film as the absorption layer in the near infrared spectrum. The fabrication of the black gold thin film was achieved by a thermal evaporation technique in N2 atmosphere. Different evaporation conditions were attempted to optimize the absorbance of the black gold coating, especially the atmosphere pressure and the mass of evaporation source. The long-standing problem of black gold’s adhesion with the substrate was solved by fuming 502 superglues into the black gold layer, which had almost no impact on the absorbance performance. Layers produced at N2 atmosphere of 3×103 Pa show an absorbance exceeding0.9 inthe near infrared.
