Abstract
is tuned ion-stoichiometrically, unlike Cs perovskites. These various synthesis pathways of pure-halide perovskite NCs enable the efficient production of high-quality perovskite NCs and allow precise tuning of the emission color to the desired wavelength. Although there are still several "gaps" remaining in the available emission wavelength, the new methodology proposed in this study could potentially be employed for manufacturing more stable perovskite NC-based optoelectronic devices.
