The aim of this work is to study optical properties of self-organised Si nanohills formed on the SiO2/Si interface after pulsed Nd:YAG laser irradiation. Nanohills on Si surface give strong photoluminescence in the visible range of spectrum, with a long wing in red portion. This property is explained by charge carrier quantum confinement in nanohills/nanowires.
