Sub-Unit Cell Growth Precision in Perovskite Quantum Dots!

28.04.2026

In our new article, we report a room-temperature solution-phase overgrowth of perovskite quantum dots with sub-monolayer precision, where discrete growth increments can be achieved either stepwise or in a quasi-continuous manner. Remarkably, the growth can be sustained for hours while retaining high monodispersity and preserving PLQY. In situ absorbance spectroscopy reveals well-controlled kinetics and four clearly resolved excitonic features. This approach opens a pathway toward atomically precise perovskite-based heterostructures for next-generation classical and quantum light technologies.
