Chemical engineering in lead halide perovskite nanocrystals (PNCs) has garnered significant attention for tailoring optoelectronic properties, such as bandgap, quantum yield (QY), and stability. Here, pure blue emissive PNCs in glass by using ultrafast laser are reported. The emission wavelength is tuned in the range from 461 to 520 nm by engineering the chemical composition in the B‐site Cd/Pb mix‐cation...
Perovskites Nanocrystals
In article number 2200902, Dexhi Tan, Jianrong Qiu, and colleagues demonstrate that by manipulating ultrafast laser‐induced liquid nanophase separation, the Cd/Pb cation concentration can be controlled at the nanoscale, and the emission wavelength of CsCdxPb1−xBr3 perovskites nanocrystals (PNCs) can be tuned within the range of 461–520 nm. The high stability and bandgap tenability...
