In this Communication, nanoparticles of the fluoridosilicates A SiF (A=Li, Na, K, Rb, Cs), which are extremely promising host lattices for future LEDs, are presented for the first time. The preparation method we introduce here is a very simple and energy and time saving one, moreover the usage of toxic HF or elemental fluorine is avoided. In detail, the ionic liquid [Bmim]PF was used both as solvent and fluoride source in an ionothermally assisted microwave synthesis. The small size of the so-obtained nanoparticles is of huge relevance for their applications as thin films or for the coverage of surfaces, for example in next-generation white LEDs upon doping with Mn .
在本通讯中，首次展示了氟硅酸盐A₂SiF₆（A = Li、Na、K、Rb、Cs）纳米颗粒，它们是未来发光二极管极具前景的主体晶格。我们在此介绍的制备方法非常简单，节省能源和时间，而且避免了使用有毒的氢氟酸或元素氟。具体而言，离子液体[Bmim]PF₆在离子热辅助微波合成中既用作溶剂又用作氟源。如此获得的纳米颗粒尺寸小，对于其作为薄膜的应用或用于表面覆盖具有重大意义，例如在掺杂锰的下一代白色发光二极管中。
