    <description descriptionType="Abstract">All inorganic colloidal halide perovskite nanoplatelets and nanowires are highly anisotropic shaped semiconductor nanocrystals with highly tunable optical properties in the visible spectrum. These nanocrystals have large exciton binding energies and high oscillator strengths due to their strongly quantum confined natures. The optical properties of the halide perovskites are tunable by variation of halide composition and morphology of the nanocrystals. We herein demonstrate that colloidal perovskite nanocrystals (NCs) placed in close proximity to chemically functionalized metal films show mixed plasmon-exciton formation, plexciton formation, in the strong coupling regime. The optical properties of all-inorganic lead halide perovskite NCs were controlled by colloidally synthesizing NCs with different morphologies such as nanowires and nanoplatelets or by controlling the composition of the halides in the NCs. The experimentally observed Rabi splitting energies are around 90 meV, 70 meV, and 55 meV for CsPbI3 nanoplatelets, CsPbI3 nanowires, and CsPb(Br/I)(3) nanoplatelets, respectively. In addition, the numerical simulations are in good agreement with the experimentally obtained data. The results show that colloidal all-inorganic halide perovskite NCs are promising and strong candidates for studying light-matter interaction at nanoscale dimension.</description>
