Synthesis of germanium nanocrystals in porous alumina by anodic oxidation of Al/Ge multi-layers

Year: 2019

Type: article

Abstract: We report synthesis of periodic Ge/Al 2 O 3 composites containing interstitial Ge nanocrystals in the walls of porous anodic aluminum oxide by anodic oxidation of Al/Ge multi-layers. The structure and luminescent characteristics of composites were investigated by transmission and scanning electron microscopy, as well as Raman and photoluminescence spectroscopy. The photoluminescence of Ge nanocrystallites was detected at ∼2.0 eV after annealing of samples in the temperature range of 500 °C–700 °C.
