N2 - Red-orange luminescent ceramic disks of La 1-XEi 2S 5AIOs (x= 1.0, 3.0. 5.0 and 10.0 at%) were prepared by the combustion synthesis method and post-annealed at high temperature. Microstructure properties were characterized by using X-ray diffraction and scanning electron microscopy. The La 1-XEu XSr 2AIO 5 X-ray diffraction patterns revealed a tetragonal phase for all the ceramic disks. Morphological analysis of the disk grains showed a mean size of 4.27 jxm. Photoluminescence emission and excitation spectra were analyzed in detail. * The x= 10.0 at%. Eu-doped ceramic sample showed the highest photoluminescence emission intensity, with a strong emission peak located at A em1 = 617 nm and a broadband with maximum excitation peak of Λ ex = 322 nm.
