Bulk Assembly of Multicomponent Zero-Dimensional Metal Halides with Dual Emission AITranslate
Abstract AITranslate
Bulk assemblies of zero-dimensional (0D) metal halides with exceptional structural versatility have enabled the development of a number of highly efficient emitters with tunable photophysical properties. Here, we report a novel single crystalline bulk assembly of multicomponent 0D metal halides, (bmpy)9[SbCl5]2[Pb3Cl11] (bmpy = 1-butyl-1-methylpyrrolidinium), which exhibits dual emissions from distinct metal halide species. Excitation-dependent warm white light emissions with high photoluminescence quantum efficiencies of >70% can be obtained by combining green emission from Pb3Cl115– and orange emission from SbCl52–. Because of complete site isolation by wide bandgap organic moieties and little-to-no spectral overlaps, no energy transfer occurs between two distinct emitting species, allowing for precise color control by manipulating the excitation wavelengths. Our discovery of dual emitting organic metal halide hybrid opens up a new way to develop precisely ordered single-crystalline multicomponent materials with multi-functionalities.
