Iribarren, A. ; Fernández Sánchez, Paloma ; Piqueras de Noriega, Javier | Academic Press Ltd- Elsevier Science Ltd | 2008-05ZnTe- and TeO_2-doped ZnO nanostructures and microstructures were obtained by a vapour-solid process by sintering compacted ZnO powder mixed with each precursor. Cathodoluminescence (CL) measurements show that if TeO_2 is used, then the defect b[...]texto impreso
Iribarren, A. ; Fernández Sánchez, Paloma ; Piqueras de Noriega, Javier | Springer Netherlands | 2008-04Sintering of a mixture of TeO_2 and ZnO powders under an Ar flux leads to the formation of elongated Te-doped ZnO nano- and microstructures on the sample surface. The growth of the structures occurs via a vapour-solid process. Cathodoluminescenc[...]texto impreso
Iribarren, A. ; Fernández Sánchez, Paloma ; Piqueras de Noriega, Javier | Wiley-V C H Verlag Gmbh | 2014-03Cathodoluminescence (CL) of Te doped elongated ZnO microstructures obtained by a vapour-solid (V-S) technique has been investigated. The CL intensity changes along the microstructures axis are related to the gradient of Te content, which influen[...]
