Resumen

Luminescence and sintering characteristics of α-Al₂O ₃-tetragonal zirconia [t-ZrO₂(Y₂O₃)] mixtures have been investigated. The pseudoboehmite is one of the main precursors of the α-alumina. In this investigation pseudoboehmite has been synthesized through a desulphatation of the commercial Al₂(SO ₄)₃ using an ammonia solution. Tetragonal zirconia powders were added in adequate proportion for each composition. The mixture constituted by Al₂O₃ (pseudoboehmite) and t-ZrO₂ has been annealed at different temperatures to obtain the crystalline phases. XRD and SEM techniques measurements have been used to structural characterization. Photoluminescence (PL) emission spectra of Al₂O₃-ZrO ₂ composites were performed at room temperature. Thermoluminescent emission spectrum of the samples was obtained and analyzed.
