                         photoacoustic spectroscopy (PAS) and photoluminescence (PL). From 
                         optical absorption data we have observed broad spectra 
                         distributions, spanning the wavelength interval, 350-850 nm, 
                         corresponding to phonon energies from 1.46 to 3.54 eV. For 
                         photoluminescence we have found a bright intensity around 360 nm. 
                         The complex energy transitions found have also been observed in 
                         porous silicon (PS) with much discussion. The amplitude and phase 
                         of the PA signals were measured at different frequencies of 
                         modulation in order to obtain the thermal diffusivity coefficient 
                         and has been obtained a value, which is about half of the 
                         crystalline silicon.",
