From: Colloidal solutions of luminescent porous silicon clusters with different cluster sizes
Results of DLS and photoluminescence measurements in colloidal solution of ‘white’ porous silicon in PBS. (a) Nanocluster size distribution of three different types of samples: black line - solution filtered with 1-μm syringe filter, red line - sample aged at ambient conditions and blue line - agglomerated sample (see text for details). (b) Corresponding photoluminescence spectra.
