Fixed Aspect Ratio Rod‐to‐Rod Conversion and Localized Surface Plasmon Resonance in Semiconducting I–V–VI Nanorods

Fixed-aspect-ratio rod-to-rod conversion of binary V-VI Sb2 Se3 to ternary I-V-VI Cu3 SbSe3 semiconducting nano structures is reported. Capturing the inter mediate products, the insight mechanisms of the ion-diffusion process for the structural transformation are established. The final ternary structure shows localized surface plasmonresonance-induced absorption in the near-infrared regions.
