A low band gap iron sulfide hybrid semiconductor with unique layered structure and unusual iron coordination exhibits significantly reduced thermal conductivity.

The abstract of this paper should read: ''We describe the efficient sensitization of lanthanide luminescence by incorporating a hydrophobic chromophore into a polymetallic micellar assembly formed by the amphiphilic lanthanide chelate. It affords screening a variety of hydrophobic chromophores and assessing the fate of micellar systems in biological media.'' Two earlier reports of intermolecular energy transfer between a chromophore and a lanthanide should have been mentioned and referenced at the end of the first paragraph:

DMSO, and en (autoclave, and characterized by single crystal XRD, XAS, and thermal conductivity measurements. The compound crystallizes in the monoclinic space group P2 1 /c with Z = 4. The structure contains a unique two-dimensional [Fe16S20] 8-layer. It is a low band gap semiconductor with an estimated band gap of about 0.6-0.8 eV, and exhibits significantly reduced thermal conductivity compared with purely inorganic FeS binary phases. -(WU, M.; RHEE, J.; EMGE, T.
