Abstract: Crystalline Mn doped ZnO nanowires were synthesized by chemical vapour deposition. The presence of Mn dopant was confirmed by X-Ray diffraction, Raman spectroscopy, transmission electron microscopy and X-Ray photoelectron spectroscopy. The photoconductivity of an individual Mn doped ZnO nanowire was investigated under different visible light excitations (532 and 405 nm). The nanowire exhibited high dark to photocurrent ratios (50), fast photocurrent response (100–250 ms), and reasonably high responsivity and external quantum efficiencies with good repeatability under different visible light illuminations. These results indicate that Mn doped ZnO nanowires would be promising for efficient multispectral photodetectors and optical switches.
