Molecular Origins of Near-Infrared Luminescence in Molybdenum and Tungsten Oxyhalide Perovskites.

ABSTRACT: Materials with near-infrared (near-IR) luminescence are desirable for applications in communications and sensing, as well as biomedical diagnostics and imaging. The most used inorganic near-IR emitters rely on precise doping of host crystal structures with select rare-earth or transition metal ions. Recently, another class of materials with intrinsic near-IR emission has been reported. The compositions of these materials were initially described as vacancy-ordered halide double perovskites Cs₂MoCl₆ and Cs₂WCl₆, but further investigation by some of us on the compound reported as Cs₂WCl₆ revealed an oxyhalide instead, with a composition Cs₂WO _x Cl_6-x , where 1 < x < 2.
