Figure 5From: Colloidal solutions of luminescent porous silicon clusters with different cluster sizesColloidal solution of standard porous silicon in methanol. (a) Size distribution of the as- prepared sample (black line), sample filtered by the 1-μm syringe filter (green line) and sample made from the sediment remained on the filter (red line) obtained by dynamic light scattering (DLS). (b) Photoluminescence spectra of all three samples.Back to article page
