TiN and ZnSiN2 nanoparticles are obtained via a novel pyridine‐based synthesis route. This one‐pot liquid‐phase route strictly avoids all oxygen sources (including starting materials, surface functionalization, solvents), which is highly relevant in regard of the material purity and material properties. Colloidally stable suspensions of crystalline, small‐sized TiN (5.4±0.4 nm) and ZnSiN2 (5.2±1.1 nm) are instantaneously available from the liquid phase. Elemental analysis and electron energy loss spectroscopy confirm the purity of the compounds and specifically the absence of oxygen. The as‐prepared ZnSiN2 show yellowish emission (500‐700 nm) already at room temperature with its maximum at 570 nm.

吡啶基液相合成结晶 TiN 和 ZnSiN2 纳米颗粒

TiN 和 ZnSiN 2纳米粒子是通过一种新型的基于吡啶的合成路线获得的。这种一锅液相路线严格避免了所有氧源(包括起始材料、表面功能化、溶剂),这与材料纯度和材料性能高度相关。可以从液相中立即获得小尺寸结晶 TiN (5.4±0.4 nm) 和 ZnSiN 2 (5.2±1.1 nm) 的胶体稳定悬浮液。元素分析和电子能量损失光谱证实了化合物的纯度,特别是不存在氧。所制备的 ZnSiN 2在室温下就显示出淡黄色发射(500-700 nm),其最大值在 570 nm。
