Effect of Material Structure on Photoluminescence Spectra from Silicon Nanocrystals

Commercially prepared (100) oriented silicon wafers were oxidized to produce SiO2 layers of 5 μm, 970 nm, 650 nm and 103 nm. Each sample was annealed at 1050°C for 1 h in a forming gas ambient. The photoluminescence (PL) emission was collected with f4
