Answer-based synthesis of combined ionic and digital conductors (MIECs) has enabled the event of novel inorganic supplies with implications for a variety of vitality storage purposes. Nonetheless, many technologically related MIECs include poisonous components (Pb) or are ready by utilizing conventional high-temperature solid-state synthesis. Right here, we offer a easy, low-temperature and size-tunable (50–90 nm) colloidal sizzling injection method for the synthesis of NaSbS2 based mostly MIECs utilizing broadly obtainable and non-toxic precursors. Key artificial parameters (cationic precursor, response temperature, and ligand) are examined to control the form and dimension of the NaSbS2 nanocrystals (NCs). FTIR research revealed that ligands with carboxylate performance are coordinated to the floor of the synthesized NaSbS2 NCs. The synthesized NaSbS2 nanocrystals have digital and ionic conductivities of three.31 × 10−10 (e−) and 1.9 × 10−5 (Na+) S cm−1 respectively, that are aggressive with the ionic and electrical conductivities of perovskite supplies generated by solid-state reactions. This analysis offers a mechanistic understanding and post-synthetic analysis of parameters influencing the formation of sodium antimony chalcogenides supplies.
