The aim of this work is to study optical properties of Si nanohills formed on the SiO2/Si interface by the pulsed Nd:YAG laser radiation. Nanohills which are self-organized on the surface of Si, are characterized by strong photoluminescence in the visible range of spectra with long wing in the red part of spectra. This peculiarity is explained by Quantum confinement effect in nanohillsnanowires with graded diameter. We have found a new method for graded band gap semiconductor formation using an elementary semiconductor. Graded change of band gap arises due to Quantum confinement effect.

New phase PbmSb2nTem+3n nanorods were synthesized using Te self-sacrifice template via Pb2+/Sb3+ synergistic effect topotactic transformation, which showed bigger band gap values due to the quantum confinement effect.
