Pérez-Salas Física, Astronomía y Matemáticas defects Nanoparticles alkali halides photoluminescence Copper atoms have been introduced by diffusion in NaCl, KCl and KBr crystals at 500±C. The crystals have been optically analyzed with photoluminescence measurements and by scanning electron microscopy. The emission and excitation spectra measured at low temperatures show the exciton confinement effect, indicating the formation of CuX (X=Cl, Br) nanoparticles, which has been confirmed by electron microscopy images. This is proposed as an alternative method to obtain CuX nanoparticles in alkali halides crystals. 2006 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57065009 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
