High Resolution Image Download MS PowerPoint Slide Color tunable light emitting lead halide perovskite nanocrystals are approaching a decade since their first synthesis, and significant progress has been achieved from understanding their formation chemistry to investigating their photophysics. However, a major wing of semiconductor nanocrystals, the epitaxial heterostructures of plasmonic noble metals with these emerged halide perovskite nanocrystals, could not be explored as expected. This poses a big question and also excites chemists to understand more on these nanocrystals. However, several other heterostructures like Pt-CsPBBr 3 and Pd-CsPbBr 3 are already reported, which opened up windows to expedite developments of all such nanocrystal heterostructures. Keeping these in mind, this prospective study brings the correlation of crystallographic orientations of different metal(0) and halide perovskite nanocrystals with the reaction chemistry to establish the ionic-metallic bonds at the interfaces for the formation of their heterostructures.
