摘要：
In this study, triethanolamine (TEOA) capped CdO nanostructures had been synthesized by wet chemical method annealed at 648 K were reported. The structural, morphological and optical properties of the samples were studied by X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM) with energy dispersive spectra (EDS) analysis, Fourier transform infrared (FTIR) spectroscopy, UV-Vis spectroscopy and Photoluminescence (PL) techniques. The XRD spectrum showed that all the samples were cubic in structure. The presence of functional groups and chemical bonding had been confirmed by FTIR. UV-Vis measurements showed decreased band gap energy for TEOA capped CdO, when compared with uncapped CdO. The PL spectra of the CdO systems showed the red emission. (C) 2015 Elsevier B.V.
