Europium (III) with different concentrations (0.2, 0.4 and 0.8 %)-TiO2 doped silica composite systems were sensitized by sol–gel method. Different spectroscopic and microscopic tools characterized the composites. The Europium ion incorporated into the liquid silica–titania solution acts as red light emission center in the luminescent materials. This(More)
