Изучение ЭПР спектров нанопористых структур анодированного оксида алюминия

Abstract

Different nanoporous structures of aluminum oxide were synthesized by anodic oxidation using electrolytes based on sulfuric, oxalic, phosphoric or hydrofluoric acids under potentiostatic mode. Photoluminescence and electron spin resonance spectra were studied at room temperature for grown samples. Values of g-factor – 2.015±0.012 – were calculated using measured signals quantitative analysis. Origin of optically active centers responsible for observed blue emission in anodized alumina was discussed taking obtained results into consideration.
