Halide perovskite nanocrystals can also stand luminescent in water

2018 
Perovskite nanocrystals (PNCs) are merging as a rising star in the field of optoelectronic materials. Apart from the great potentials in display, photovoltaics and optical sensors, etc., they may become an alternative choice of conventional cadmium chalcogenides, e.g., CdSe and CdTe quantum dots (QDs), for biological and biomedical applications. Nevertheless, the extremely moisture-sensitive nature of halide perovskites set a huge hurdle towards the latter applications as well as other possible applications in humid environments.
