Abstract: This paper focuses on the sol-gel preparation and spectroscopic characterization of transparent and rare earth-doped TiO 2 monoliths, for further applications in luminescence. The preparation method was based on a sol-gel technique applied to titanium isopropoxide as the precursor. By controlling the hydrolysis of this precursor by the intermediate of an esterification reaction, and by also controlling the rate of drying, transparent TiO 2 xerogel monoliths were obtained at room temperature. The monoliths pre…
