In the rapidly evolving field of nanotechnology, metal@semiconductor core-shell heterostructures have garnered significant attention for their unique optical and electronic properties. These structures offer immense potential for enhancing light harvesting and tuning the localized surface plasmon resonance (LSPR). However, the lack of a universal and scalable synthetic method for constructing diverse semiconductor shells remains a major challenge. In this study, we report for the first time a versatile low-temperature two-step method for fabricating hollow gold nanoparticles (HGNs)@semiconductor core-shell heterostructures. By employing mercaptobenzoic acid (MBA) as a linker molecule and polyvinylpyrrolidone (PVP) as a stabilizing agent, this method enables the uniform deposition of various semiconductors, including CuO, Fe
