Rodríguez Rojas R. Chiu-Zárate Física, Astronomía y Matemáticas spectroscopy spectroscopy spectroscopy Erbium nanoparticles Erbium nanoparticles Er2O3 nanoparticles were synthesized by co-precipitation with the addition of ascorbate as stabilizing agent. The nanoparticles had spherical shapes with a mean diameter of 32 nm and were allocated in clusters, as determined by XRD, AFM, and optical microscopy. Characteristic green and red emissions from Er3+ were recorded by pumping the nanoparticles at 525 nm, 805 nm, and 975 nm. However, the luminescence spectra show an enhancement of red emission for NIR pump wavelengths. We proposed this behavior was due to phonon-assisted depopulation mechanisms and energy transfer processes related to the different excitation schemes. 2015 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57036862010 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
