Al 2 O 3 :Eu 3+ (1%) samples were prepared by combustion, ceramic, and Pechini methods annealed from 400 to 1400 ยฐC. XRD patterns indicate that samples heated up to 1000 ยฐC present disordered character of activated alumina (c-Al 2 O 3 ). However, a-Al 2 O 3 phase showed high crystallinity and thermo
