摘要: Manganese (Mn) doping of ZnS nanoribbons was achieved by simple thermal annealing. Upon heating with MnS powder up to 700°C, the intrinsic photoluminescence (PL) annealed disappeared and a new PL peak at 585nm gradually emerged. Significantly, annealing process induced no detectable change in morphology uniform hexagonal wurtzite 2H structure single-crystal nanoribbons. The is attributed Mn dopant confirms incorporation because (1) appears only when ribbons were MnS, but does not appear without (2) its intensity increases increasing temperature, which consistent increased Mn2+ ions, (3) position similar that Mn-related emission ZnS, independent measuring temperature excitation power. This work demonstrates capability nanostructured materials postannealing treatment.
