Broadband Optical Absorber Based on Nano-patterned Metallic Glass Thin Films.
JOURNAL OF PHYSICAL CHEMISTRY LETTERS(2019)
摘要
Applications of metallic glass thin films (MGTFs) in the optical area have seldom been reported. We successfully design and fabricate a broadband and durable absorber with MGTFs. It is found that the absorber, with a total thickness of only similar to 230 nm smaller than the light wavelength, exhibits excellent performance, that is, an average absorption of >90% from the visible to the near-infrared range (500-1300 nm). This is of significance for the optical application of MGTFs with the potential for large-scale fabrication using superplastic deformation in the supercooled liquid region of MGTFs.
