Peculiarities of Photoluminescence in Porous Silicon Prepared by Metal-Assisted Chemical Etching

Figure 5

Photoluminescence spectra as a function of the deposition time taken from Ag-assisted chemically etched silicon. Etching was performed in solution—H2O2/H2O/HF = 10/80/40 within 10 min. Ag particles were deposited before etching in solution 0.23 M HF and 5 × 10−5 M AgNO3.
