Abstract
Ho3+: Yb3+ ions doped highly transparent SiO2- TiO2 nano-composite were successfully fabricated in the forms of monolith and thin films. the preparations were carried out via a modified sol-gel method at different annealing temperatures ranging from 500oC up to 1000oC for 3h. The structural and optical properties were determined by XRD, FESEM, 3D laser Raman and FTIR spectroscopy. The thickness of the thin film sample doped with 0.4 mol % of Ho3+ ions and co-doped with 0.5mol % of Yb3+ was measured 1.3 m using the cross-section Field emission scanning electron microscopy (FESEM) technique. These results suggest that the Ho3+: Yb3+ silica-titania are promising candidates for photonic devices.
