Sánchez, B ; Méndez Martín, Bianchi ; Piqueras de Noriega, Javier ; Sirbu, L. ; Tiginyanu, I. ; M., I. ; Ursaki, V.V. | Springer Netherlands | 2008-01Porous GaP layers doped with erbium or europium elements have been obtained by electrochemical etching and further impregnation processes. The thermal treatments for optical activation of rare earth (RE) ions lead to partial oxidation of porous [...]texto impreso
Hidalgo Alcalde, Pedro ; Piqueras de Noriega, Javier ; Sirbu, L. ; Tiginyanu, M. | IOP publishing ltd | 2005-12The luminescence of porous InP prepared by electrochemical etching is investigated by cathodoluminescence (CL) in a scanning electron microscope (SEM). Anodization causes a strong reduction of CL intensity as well as a blue spectral shift. Addit[...]
