Herein, we report a robust strategy to synthesize high\u2010quality SWIR InAs CQDs by introducing bulky oleic acid (OA) ligands to overcome these kinetic barriers. By modulating the interplay between the steric hindrance of OA ligands and the stabilization of (111) facets, we induce a controlled shape evolution from initial kinetically stabilized spheres to thermodynamically stable tetrahedrons. This morphological transition enables the achievement of the same absorption wavelength followed by a nearly fourfold reduction in nanocrystal volume compared to spherical counterparts. This mechanism offers a distinct pathway for the bandgap tunability of InAs CQDs enabling access to the SWIR region (&gt;1700\u00a0nm) under mild reaction conditions (260\u2013280\u00b0C). Furthermore, the OA\u2010mediated surface chemistry unlocks the formulation of conductive halide\u2010based inks, enabling photodetector development based on amino\u2010arsine\u2010synthesized InAs CQDs extending their spectral coverage to 1.6 um. The resulting photodetectors exhibit an external quantum efficiency of 19.1% at 1300\u00a0nm and\n                    <jats:italic>D<\/jats:italic>\n                    * of 3.4 \u00d7 10\n
