Abstract

Rhenium chalcohalide cluster compounds are a photoluminescent family of mixed-anion chalcohalide cluster materials. Here we report the new material Rb₆Re₆S₈I₈, which crystallizes in the cubic space group Fm (Formula presented.) m and contains isolated [Re₆S₈I₆]⁴⁻ clusters. Rb₆Re₆S₈I₈ has a band gap of 2.06(5) eV and an ionization energy of 5.51(3) eV, and exhibits broad photoluminescence (PL) ranging from 1.01 eV to 2.12 eV. The room-temperature PL exhibits a PL quantum yield of 42.7% and a PL lifetime of 77 μs (99 μs at 77 K). Rb₆Re₆S₈I₈ is found to be soluble in multiple polar solvents including N,N-dimethylformamide, which enables solution processing of the material into films with thickness under 150 nm. Light-emitting diodes based on films of Rb₆Re₆S₈I₈ were fabricated, demonstrating the potential for this family of materials in optoelectronic devices.

This work is supported in part by the National Science Foundation through the MRSEC program (NSF-DMR 1720139) at the Materials Research Center and in part through DMR-2305731. The work made use of the IMSERC Physical Characterization facility at Northwestern University, which has received support from the Soft and Hybrid Nanotechnology Experimental (SHyNE) Resource (NSF ECCS-2025633) and from Northwestern University. It also made use of the EPIC and Keck-II facilities of Northwestern University’s NUANCE Center, which have both received support from the SHyNE Resource (NSF ECCS-2025633), the IIN and Northwestern’s MRSEC programme (NSF DMR-1720139). The work made use of the GIANTFab core facility at Northwestern University. GIANTFab is supported by the Institute for Sustainability and Energy at Northwestern and the Office of the Vice President for Research at Northwestern. Photoemission yield spectroscopy in air measurements were carried out with equipment acquired using ONR grant N00014-18-1-2102. This research used resources of the Advanced Photon Source Beamline 8-ID-E, a US Department of Energy (DOE) Office of Science User Facility operated for the DOE Office of Science by Argonne National Laboratory under contract DE-AC02-06CH113. We acknowledge M. Quintero, D. Chica and R. McClain for productive conversations.
