Description
Summary:Abstract 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.
