In this work, we obtained porous silicon with different porosity by electrochemical etching and studied their photoluminescence. Two well-known photoluminescence mechanisms of porous silicon related to the composition and morphology of the surface have been discovered, and it has been established at what porosity values they prevail. It is shown that an increase in the porosity index leads to an increase in the intensity of photoluminescence.
