Abstract
Several new and useful compositions of rare earth oxides and mixtures of rare earth oxides are made into strong flexible fibrous textiles and strands. By varying the mixtures of rare earth metal oxides that make up the textiles and strands, the emission spectra can be matched to the absorption spectra of a variety of semiconductor photovoltaic cells. Furthermore, the addition of between 1-10 mol % of thorium oxide to the rare earth metal oxide fibers inhibits microcrystalline grain growth at high temperatures.
