In this letter, we report a simple process to derive in situ surface stabilised intrinsic CdSe nanoparticles (NPs) showing room temperature ferromagnetism (RTFM). The observed RTFM is primarily attributed to the lattice strain (ε) in the NPs supported by an effective core (CdSe)-shell (surface layer) charge transfer mechanism. The synthesis method allows precise control over particle morphology and dispersity, and is highly convenient in tuning the magnetic properties for pertinent applications. Highlights Magnetic CdSe nanoparticles were synthesized by a facile process. In situ formed graphitic-carbon layer on the surface stabilises the nanoparticles. The process permits precise control over particle morphology and dispersity. The technique is also convenient in tuning the magnetic properties. Monodispersed magnetic CdSe nanoparticles have potential applications in modern optoelectronics. GRAPHICAL ABSTRACT

通过简单的过程在表面稳定的本征 CdSe 纳米粒子中诱导铁磁性

在这封信中，我们报告了一个简单的过程来获得显示室温铁磁性 (RTFM) 的原位表面稳定的本征 CdSe 纳米粒子 (NPs)。观察到的 RTFM 主要归因于有效核 (CdSe)-壳 (表面层) 电荷转移机制支持的 NP 中的晶格应变 (ε)。该合成方法可以精确控制颗粒形态和分散性，并且非常方便地为相关应用调整磁性。亮点 磁性 CdSe 纳米颗粒是通过简单的工艺合成的。在表面原位形成的石墨碳层稳定纳米颗粒。该过程允许对颗粒形态和分散性进行精确控制。该技术在调整磁性方面也很方便。单分散的磁性 CdSe 纳米粒子在现代光电子学中有潜在的应用。图形概要
