Water-dispersed silicon nanoparticles (SiNPs) are facilely prepared in an aqueous phase via microwave-assisted synthesis. The whole synthetic procedure is accomplished in a one-pot microwave reaction, without the requirement of additional surface modification. Remarkably, the resultant SiNPs feature ultrahigh fluorescence (photoluminescent quantum yield (PLQY): ∼90%), robust pH- and photo-stability, and favourable biocompatibility.
水相分散硅纳米颗粒（SiNPs）可通过微波辅助合成在水相中简便制备。整个合成过程在一锅微波反应中完成，无需额外的表面改性。值得注意的是，所得 SiNPs 具有超高荧光（光致发光量子产率（PLQY）：~90%）、强酸碱和光照稳定性以及良好的生物相容性。
