Web9 apr. 2024 · 1.1.Defects in g-C 3 N 4. Crystallographic defects are generated in a material via a change in the periodic arrangement of ions or atoms in a crystalline structure [28].Several different forms of defects have been classified based on their dimensions; for example, the point defects group includes vacancies, replacement defects, interfacial … Web13 jan. 1999 · Porous silicon (PS) with strong and nondegrading photoluminescence (PL) is prepared by iron-passivating hydrothermal etching. The PL peak intensity of freshly as-prepared PS is as ∼2 times strong as that of conventionally anodized PS. This peak intensity reaches a saturation after the samples are annealed at 120 °C for ∼3 h, which …
