Toward Precision Nanochemistry in Halide Perovskite Quantum Dots

Halide perovskite nanochemistry is evolving at an unprecedented pace, rapidly expanding the scope of these materials from fundamental model systems to platforms with growing impact across both classical and quantum light technologies. In this perspective, we follow perovskite quantum dots (pQDs) from their birth in solution to their fully developed structural and photophysical complexity, highlighting recent advances, offering a critical view on current limitations, and discussing open questions together with possible paths forward. We hope this perspective helps inspire the next generation of ideas, tools, and design principles needed to unlock the full potential of pQDs.
