    Pulverized porous silicon is used to prepare colloidal suspensions of silicon nanocrystals in various organic solvents including xylene. The spectra this suspension show a slow evolution from the original orange color through blue to a yellow one. After approximately 5 weeks, a yellow emitting transparent colloidal solution can be extracted from the cuvette, with a high and stable photoluminescence yield (20%).
