Abstract
As a promising material which has excellent PL properties, caesium lead bromide perovskite is a great candidate for numerous applications, yet most caesium lead bromide perovskites intrinsically lack water resistance. Here, we report the developing of the highly desired aqueous perovskite nanocrystals. We successfully developed a modified re-precipitation protocol which is promising in stabilizing and solubilizing the potential aqueous PNCs. Using the method, stable green-emitting aqueous PNCs, L-31-PNCs, were synthesized which exhibits excellent stability, marking the viability of our strategies.
Moreover, we are able to synthesize aqueous reduced-dimensional caesium lead bromide perovskite has long been hindered by severe water stability issue. Based on the developed approach, the aqueous quantum-confined PNCs (QCPNCs) were synthesized for the first time. Characterizations suggest our samples exhibited noticeable stability under storage and under UV light, paving the way for the research and application of the aqueous QCPNCs.
