Evolution of free volumes in polycrystalline baga2o4 ceramics doped with eu3+ ions
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)BaGa2O4 ceramics doped with Eu3+ ions (1, 3 and 4 mol.%) were obtained by solid-phase sintering. The phase composition and microstructural features of ceramics were investigated using X-ray diffraction and scanning electron ... -
Positron annihilation lifetime spectroscopy insight on free volume conversion of nanostructured MgAl2 O4 ceramics
(Multidisciplinary Digital Publishing Institute (MDPI), 2021)Herein we demonstrate the specifics of using the positron annihilation lifetime spectroscopy (PALS) method for the study of free volume changes in functional ceramic materials. Choosing technological modification of ...
