Summary
We developed a broadband absorber using metallic glass thin films (MGTFs). This durable, thin-film absorber achieves over 90% absorption across visible to near-infrared wavelengths.
Area of Science:
- Materials Science
- Optics
- Nanotechnology
Background:
- Metallic glass thin films (MGTFs) have limited reported applications in optics.
- Developing novel optical materials with broadband absorption is crucial for various technologies.
Purpose of the Study:
- To design and fabricate a broadband and durable absorber utilizing MGTFs.
- To evaluate the optical performance of the MGTF absorber across visible to near-infrared spectra.
Main Methods:
- Fabrication of a broadband absorber using metallic glass thin films.
- Characterization of the absorber's optical properties, including absorption spectra and thickness.
Main Results:
- The MGTF absorber, with a thickness of ~230 nm, demonstrated excellent broadband absorption (>90% average) from 500-1300 nm.
- The absorber exhibits durability, a key factor for practical optical applications.
Conclusions:
- MGTFs are suitable for creating highly efficient, thin-film broadband absorbers.
- The findings highlight the potential of MGTFs for optical applications, particularly with scalable fabrication methods like superplastic deformation.
