Abstract ： Electronic properties are investigated for three alumina polymorphs (corundum, Rh2 O3 (II) and Pbnm perovskite), which are predicted as the stable structures under different pressure range, by means of the first-principles molecular dynamics method within local density functional framework. The similarity in electronic properties of the polymorphs of alumina is observed. The effect of possible phase transitions on ruby (Cr+3 -doped Al2 O3 ) fluorescences is discussed.
