Structure-Property Correlation and Strong Electronic Cross-Talk in Low Dimensional Metal Halide Hybrids

Low dimensional (2D, 1D, 0D) metal halide hybrids, supporting strongly bound excitons, show narrow band edge and broadband self-trapped excitonic (STE) emission. In the absence of general guidelines to enhance this broadband emission, structure-property correlation can be beneficial in designing highly emissive materials. This talk will highlight the fundamental factors that control the emissive properties of main group ns² metal halide based low dimensional (1D, 0D) hybrids. Our current results on utilizing doping strategy for the synthesis of multi-metallic halide hybrids that manifest interesting photo-physical properties and structural control will be showcased. Effects of electronic interaction between the metal halide units in such multi-metallic low dimensional hybrids will be highlighted. Mechanism of the electronic cross-talk between the isolated metal halide units in such systems will be discussed. Utility of such multi-metallic halide hybrids for anti-counterfeiting and negative thermal quenching applications will be highlighted. The talk will conclude with outlook of our current research work highlighting the existing issues in white light emission using main group low dimensional metal halide hybrids.
