dc.description.abstractThe growth of materials via the sol-gel method offers a viable alternative to traditional high temperature melt growth processes. The sol-gel process is a wet chemical method for producing solid inorganic materials from solutions. Sol-gel technology has evolved considerably over the last decade and founds its way in a wide range of practical applications from catalyst support, to thermal insulation, from solar cells to oxygen food sensors or sunscreen formulations. The sol-gel process can be used to produce alumina, Al2O3, in a variety of forms from porous, transparent monoliths to ceramics. In addition, the sol-gel growth technique enables the doping of transition alumina with precise amounts of optically active impurity ions. These ions probe the structure and dynamics of the materials through interactions with the crystal field produced by the host ions. In this work, we report on the luminescent properties of chromium and manganese ions doped in alumina. The goal of this dissertation is to produce Cr3+ and Mn4+ doped in alumina using sol-gel technique and to acquire a fundamental knowledge in the area of luminescence spectroscopy.
