| Abstract: | In this work, the successful synthesis of ZnSe nanowires using alumina template by simple and facile electroless template technique has been reported. Morphological characterization of the synthesized nanowires has been done by X-ray diffraction (XRD) and scanning electron microscopy (SEM) measurements. The optical characterizations were conducted by UV–visible and time resolved photo-luminescence. Grain size of synthesized ZnSe nanowires was also calculated using the XRD results. The calculated crystallite size was found to be 6.80 nm. SEM analysis confirms the fabrication of nanowires successfully and it also confirms the size of the nanowires as per the template parameters. The calculated band gap value of 3.03 eV shows the origin of quantum confinement effect in ZnSe nanowires even at the 100 nm scale. The time resolved photoluminescence result indicates that the ZnSe nanowires can be a promising material for luminescent applications in micro-second time domain. |
