Template Selection Strategy for Synthesis of One-Dimensional CrSbSe<sub>3</sub> Ferromagnetic Semiconductor Nanoribbons
CrSbSe<sub>3</sub>─the only experimentally validated one-dimensional (1D) ferromagnetic semiconductor─has recently attracted significant attention. However, all reported synthesis methods for CrSbSe<sub>3</sub> nanocrystals are based on top-down methods. Here we report a template selection strategy for the bottom-up synthesis of CrSbSe<sub>3</sub> nanoribbons. This strategy relies on comparing the formation energies of potential binary templates to the ternary target product. It enables us to select Sb<sub>2</sub>Se<sub>3</sub> with the highest formation energy, along with its 1D crystal structure, as the template instead of Cr<sub>2</sub>Se<sub>3</sub> with the lowest formation energy, thereby facilitating the transformation from Sb<sub>2</sub>Se<sub>3</sub> to CrSbSe<sub>3</sub> by replacing half of the Sb atoms in Sb<sub>2</sub>Se<sub>3</sub> with Cr atoms. The as-prepared CrSbSe<sub>3</sub> nanoribbons exhibit a length of approximately 5 μm, a width ranging from 80 to 120 nm, and a thickness of about 5 nm. The single CrSbSe<sub>3</sub> nanoribbon presents typical semiconductor behavior and ferromagnetism, confirming the intrinsic ferromagnetism in the 1D CrSbSe<sub>3</sub> semiconductor.
