Structural, optical and magnetic resonance properties of TiO2 fibres grown by l...
Rodrigues, Joana; Peres, Marco; Fernandes, António; Graça, Manuel; Sobolev, Nicolai; Costa, Florinda; Monteiro, TeresaTiO2 fibres grown by the laser floating zone technique show the rutile crystalline phase as identified by X-ray diffraction and Raman spectroscopy. Scanning electron microscopy evidences a uniform surface, free of inclusions and without low-angle grain boundaries and bubbles. At low temperatures, the fibres luminescence is dominated by a richly structured optical centre with two well-defined zero-phonon lines a...
