| Abstract: | An effective solvothermal reaction route has been developed for large-scale synthesis of CdS nanowires. L-cysteine was used
as both sulfur source and capping reagent. The nanowires obtained were characterized by XRD, SEM, TEM, HRTEM, UV-Vis and PL.
On the basis of time-resolved experiments, a possible growth mechanism was proposed. FTIR analysis confirmed the formation
of Cd-cysteine complex and peptide during the reaction. The mechanism was further supported by comparative experiments with
other sulfur sources.
