Photoluminescence properties of individual porous silicon nanoparticles are investigated and related to the macroscopic performance of the SiO2 passivated Si nanocrystals. Combined application of both wide-field imaging microspectroscopy and confocal single-photon-counting microscopy enables detection of spectra of individual nanocrystals within porous Si grains and study of their on–off blinking statistics.
