Hg‐doped CdS nanowires with an average diameter of ∼10–15 nm and lengths up to hundreds of micrometers are fabricated by chemical vapor reaction. The as‐synthesized products have a single crystal phase and grow along the 〈001〉 direction. The growth of Hg‐doped CdS nanowires is suggested for the quasi‐vapor–solid mechanism (QVSM). In particular, the PL spectra show enhancing emission peaks that strongly shift to long wavelengths (up to 115 nm redshift) with Hg doping where the Hg‐doped CdS nanowires are found to be responsible for the different characteristics; the PL mechanism is explained in detail.
