Description:

Various types of light emitting materials have been developed, including organic and polymeric emitters, transition metal complexes, rare-earth doped phosphors, nanocrystals, and organic-inorganic hybrid perovskites.

Organic-inorganic metal halide hybrids are a class of crystalline materials that may have unique structures and/or permit the tenability of one or more properties. Metal halide polyhedra can form three- (3D), two- (2D), one- (1D), and zero-dimensional (0D) structures surrounded by organic moieties. The decreased dimensionality of the inorganic structures can lead to the emergence of unique properties. For example, unlike narrow emissions with a small Stokes shift that has been observed in typical 3D metal halide hybrids, broadband photoluminescence with a large Stokes shifts has been realized in corrugated-2D, 1D, and 0D metal halide hybrids, likely due to exciton self-trapping or excited state structural deformation.

This invention comprises a bulk quantum material. In some embodiments, the bulk quantum material includes two or more photo- and/or electro-active species; and a wide band gap organic network comprising a plurality of organic cations; wherein each of the two or more photo- and/or electro-active species are (i) disposed in the wide band gap organic network, and (ii) isolated from each other. In some embodiments, the two or more photo- and/or electro-active species comprise two or more metal halide species.
