Water-resistant perovskite nanodots enable robust two-photon lasing in aqueous environment

Water-resistant perovskite nanodots enable robust two-photon lasing in aqueous environment

Lead halide perovskite quantum dots (PQDs) promise applications in optoelectronics but are limited by sensitivity to wet environments. Here the authors develop a Pb-S bonding approach to synthesize PQDs@silica nanodots that are capable of emitting and lasing in aqueous environments for long periods.
