Abstract
Bulk assemblies are provided, which may have desirable photoluminescence quantum efficiencies. The bulk assemblies may include two or more metal halides, and a wide band gap organic network. The wide band gap organic network may include organic cations. The metal halides may be disposed in the wide band gap organic network. Light emitting composite materials also are provided.
Claims9
A light emitting composite material comprising:
- a first bulk assembly in particulate form;
- a second bulk assembly in particulate form;
- and
- a matrix material, wherein the first bulk assembly and the second bulk assembly are dispersed in the matrix material;
- wherein the first bulk assembly comprises two or more first metal halides and a first wide band gap organic network, the first wide band gap organic network comprising a plurality of first organic cations, wherein the two or more first metal halides are (i) disposed in the first wide band gap organic network, and (ii) isolated from each other;
- and
- wherein the second bulk assembly comprises two or more second metal halides and a second wide band gap organic network, the second wide band gap organic network comprising a plurality of second organic cations, wherein the two or more second metal halides are (i) disposed in the second wide band gap organic network, and (ii) isolated from each other;
- wherein (A) (a) the two or more first metal halides comprise a tetrahedron of formula MnX42−, (b) the plurality of first organic cations comprises Ph4P+, and (c) the first bulk assembly has the following formula—
- (Ph4P)2MnX4,
- wherein X of the two or more first metal halides is selected from the group consisting of Cl, Br, and I, or
- (B) (a) the two or more second metal halides comprise an octahedron of formula SnX64−, (b) the plurality of second organic cations comprises C4N2H14X+, and (c) the second bulk assembly has the following formula—
- (C4N2H14X)4SnX6,
- wherein X of the two or more second metal halides is selected from the group consisting of Cl, Br, and I.
