ScholarBank@NUS Repository. https://doi.org/10.1016/j.jallcom.2011.09.018 | Abstract: | Highly crystalline P-doped ZnO nanowires were grown by physical vapour transport technique without presence of any catalysts. Grown nanowires were well aligned and had good crystallinity with evolution of preferred orientation (0 0 2). Both EDX and Rutherford backscattering spectrometry (RBS) results revealed that phosphorus atoms were incorporated in the ZnO nanowires with the content of less than 1%. The XRD results confirmed an increase in lattice spacing which is attributed to substitution of P on oxygen sites. The photoluminescence spectra of grown nanowires showed a strong emission peak at 3.248 eV with a shoulder at 3.184 eV, corresponding with FA (free electron to acceptor) and DAP (donor-acceptor pair) levels of P-doped ZnO. The lattice spacing from HRTEM agrees with the achieved results from XRD measurement. © 2011 Elsevier B.V. | Source Title: | Journal of Alloys and Compounds | URI: | http://scholarbank.nus.edu.sg/handle/10635/98175 | ISSN: | 09258388 | DOI: | 10.1016/j.jallcom.2011.09.018 |
