Zero-dimensional organic-inorganic hybrid zinc halide with broadband yellow light emission
In recent years, low-dimensional organic-inorganic hybrid metal halides have attracted great attention in the field of solid-state optical materials due to their outstanding luminescence properties. Here, one new zero-dimensional (0D) hybrid zinc bromide [ N -EPD] 2 ZnBr 4 ( N -EPD = N -ethylpyridin...

Zusammenfassung: | In recent years, low-dimensional organic-inorganic hybrid metal halides have attracted great attention in the field of solid-state optical materials due to their outstanding luminescence properties. Here, one new zero-dimensional (0D) hybrid zinc bromide [

consists of a discrete [ZnBr

tetrahedron and organic [

ZnBr

displays strong yellow broadband luminescence with a promising photoluminescence quantum yield (PLQY) of 8.28%. Based on temperature-dependent, time-resolved spectroscopy characterization and theoretical studies, the broadband yellow emission can be attributed to radiative recombination of self-trapping excitons (STEs). To the best of our knowledge, this is the first report about yellow light emission in 0D hybrid zinc halides.
