摘要: The intense luminescence observed for porous silicon [1] has raised extremely interesting problems related to the possibility of using in optoelectronics. One likely explanation is quantum confinement, induced by formation nanocrystallites. However, experimental data reveal a complex situation characteristic several radiative as well non channels. Our main aim this chapter will thus be review relevant theoretical information concerning optical properties Si nanocrystals order identify these
