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

Figure 8

Photoluminescence spectra as a function of the deposition time taken from Ag-assisted chemically etched silicon. Etching was performed in solution—H2O2/H2O/HF = 15/80/40 within 6 min. Ag particles were deposited before etching in solution 0.23 M HF and 10−3 M AgNO3.
