Agglomeration of luminescent porous silicon nanoparticles in colloidal solutions
Original language description
We have prepared colloidal solutions of porous silicon nanoparticles in methanol, water and Phosphate Buffered Saline (PBS). Even that the size of the nanoclusters is between 60-500 nm, due to their highly porous structure the nanoparticles show strong visible luminescence in the orange-red spectral region. Hydrophilic behavior and good solubility of the nanoclusters in water and water-based solutions was obtained by adding hydrogen peroxide into the etching bath during preparation. By simple filtration of the solutions with syringe filters we have extracted smaller nanoclusters with sizes of approx. 60-70 nm. When the samples were left at ambient conditions for several weeks, the typical nanocluster size increased to approx. 330-400 nm and then remained stable. However, both freshly filtered and agglomerated samples of porous silicon in water and PBS solutions can be further used for biological studies such as for biocompatibility or as luminescent markers in living cells.
