Abstract EN
Nanostructured ZnO was deposited on different substrates (Si, SiO2, and Au/SiO2) by an enhanced physical vapor deposition technique that presents excellent luminescent properties.
This technique consists in a horizontal quartz tube reactor that uses ultra-high purity Zn and UHP oxygen as precursors.
The morphology and structure of ZnO grown in this work were studied by electron microscopy and X-ray diffraction.
The XRD patterns revealed the highly crystalline phase of wurtzite polycrystalline structure, with a preferred (1011) growth direction.
Room temperature cathodoluminescence studies revealed two features in the luminescence properties of the ZnO obtained by this technique, first a high-intensity narrow peak centered at 390 nm (~3.2 eV) corresponding to a near band-to-band emission, and secondly, a broad peak centered around 517 nm (2.4 eV), the typical green-yellow luminescence, related to an unintentionally doped ZnO.
