Herein, we propose a polaron engineering strategy to circumvent the EG law via accelerating the radiative recombination rate by 150\u2010fold through increased charge localization. By incorporating Nd\n                    <jats:sup>3+<\/jats:sup>\n                    into CdTe quantum dot lattice, we achieved broadband NIR\u2010IIb\/c emission peak at 1730\u00a0nm, with PLQY of 11.34 \u00b1 0.79% in aqueous solution and a Stokes shift exceeding 900\u00a0nm. We demonstrate Nd\n                    <jats:sup>3+<\/jats:sup>\n                    substitution introduces beneficial defects that perturb electronic structure and local symmetry. Upon 808\u00a0nm excitation, these defects trap photoexcited carriers, inducing lattice distortions and strong electron\u2010phonon coupling, which leads to the formation of polarons with high NIR\u2010II emission efficiency. The resulting QDs enable clinical\u2010grade NIR\u2010II imaging via dual modes, including low\u2010power (10\u00a0mW cm\n                    <jats:sup>\u2212<\/jats:sup>\n                    <jats:sup>2<\/jats:sup>\n                    ) real\u2010time deep\u2010tissue imaging and white\u2010light\u2010activatable fluorescence\u2010guided surgery navigation. This study provides a promising approach to bypass the EG law, offering a pathway toward highly emissive emitters in the NIR regime.\n
