Weiling Dong et al. has publsihed a paper in the Journal of Physical Chemistry C which describes how plasmonic nanogratings can be combined with phase change materials to create strong absorption in the visible spectrum. Weiling explained that the simple design of her structure will enable mass production of these super absorbers.
The research was conducted in collaboration with Prof Tun Cao of Dalian University of Technology, China.
ACTAlab is developing tuneable optical filters based on chalcogenides for a wide range of applications from displays to pollution detectors.
