The interest on strongly emitting colloidal perovskite nanoparticles has been arisen explosively since several years. The versatility of the synthesis and the resulting scale-up, as well as high performance in terms of photoluminescence quantum yields and narrow spectra make these nanocrystals extremely attractive in optoelectronics. However, commonly known instability of these nanoparticles in aqueous environment is an important issue limiting their applications. This letter highlights a recent report by Geng et al. presenting direct aqueous synthesis of strongly emitting perovskite nanocrystals. One can foresee extrapolation of these results toward other perovskites including those based on Pb-free materials.
