摘要：
The present work is based on the comparative study of structural, spectral, and thermal characterization of zinc oxide nanowire (ZnO NW) synthesized through the thermal decomposition method, once microwave-assisted and once in ambient air. The structural morphology and crystalline nature were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD). The spectral characterization was studied by using optical absorption (UV-Vis) and photoluminescence (PL) at room temperature. Their optical absorption exhibits defect-induced fluorescence tunable behaviour.
