Description

We report synthesis of periodic Ge/Al2O3 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. (paper)
