Nanosecond Optical Limiting Property of a Novel Octanuclear Silver Cluster Complex Containing Arylselenolate Ligands

A silver complex with excellent optical limiting properties is presented by the authors (see Figure). A threshold fluence of 0.2 J cm–2 at 532 nm (2.5 times less than that of C60) and a signal suppression ability comparable to that of organic two-photon absorbers make the Ag8Se8-based complex promising for broadband optical limiting applications.
