卤化铅钙钛矿纳米晶因其优异的光学性能而受到广泛关注,但其环境稳定性差以及传统合成路径中存在高毒性问题仍制约着其实际应用。本文提出在水/油两相中通过超声诱导策略,在介孔硅微球(MS)中原位合成包覆的CsPbBr

(CsPbBr

@MS)复合材料。在该方法中,无配体的CsBr水溶液与预先分散在介孔硅微球中的油酸铅在超声波的作用下,实现了离子由水相向油相介孔中扩散,在介孔硅微球中原位成核并最终封装CsPbBr

@MS复合材料表面构建了致密的SiO

壳层,显著提升了光学稳定性。经过水中浸泡60 h后,该材料的发射强度仍可保持初始值的80%。该工作为绿色合成稳定、高性能钙钛矿纳米材料提供了新策略。
Lead halide perovskite nanocrystals have garnered significant interest due to their exceptional optical properties. However, their poor environ
mental stability and the toxicity of conventional synthetic methods continue to impede practical applications. In this study, we report a novel ultrasound-assisted, green water/oil biphasic strategy for the in situ synthesis of CsPbBr
3
nanocrystals encapsulated within mesoporous silica microspheres (CsPbBr
3
@MS). In this approach, ligand-free CsBr dissolved in water diffuses into the oil phase under ultrasonic agitation, where it reacts with oleic acid-coordinated Pb
2+
species preloaded in the silica mesopores, resulting in confined nucleation and encapsulation of CsPbBr
3
NCs within the silica framework. Optical characterization and stability assessments demonstrate that mesoporous encapsulation substantially enhances both the photoluminescence properties and environmental stability of CsPbBr
3
@MS. Furthermore, tuning the aqueous CsBr concentration enables optimization of the optical output, yielding a maximum photoluminescence quantum yield(PLQY) of up to 60%. A dense SiO
2
shell was subsequently formed on the composite surface via TEOS, facilitated by trace water within the mesopores. This secondary passivation layer further improved optical durability, retaining 80% of the initial emission intensity after 60 h of water immersion. Overall, this work presents a green and effective strategy for synthesizing environmentally stable, high-performance perovskite nanomaterials.
