Tóm tắt

The development of sustainable and tunable materials is crucial for advancing modern technologies. We present a controlled synthesis of colloidal Na-Cu-S nanostructures. To overcome the reactivity difference between Na and Cu precursors toward chalcogens in a colloidal synthesis and to achieve metastable phase formation, we designed a single-source precursor for Cu and S. The decomposition of this precursor creates a Cu-S template into which Na ions diffuse to form metastable Na-Cu-S. By leveraging the reactivity of sulfur precursors, we synthesized Na
