    • AgSn[Bi1-xSbx]Se-3: Synthesis, Structural Characterization, and Electrical Behavior 
      Valencia Gálvez, Paulina; Delgado, Daniela; López, María Luisa; Álvarez Serrano, Inmaculada; Moris, Silvana; Galdámez Silva, Antonio César (MDPI, 2021)
      Herein, we report the synthesis, characterization, and electrical properties of lead-free AgSnm[Bi1-xSbx]Se2+m (m = 1, 2) selenides. Powder X-ray diffraction patterns and Rietveld refinement data revealed that these selenides ...
    • Surface-enhanced luminescence of Cr3+-doped ZnAl2O4 and MgAl2O4 using Ag@SiO2 and Au@SiO2 core-shell nanoparticles 
      Valenzuela Fernández, Rodrigo Andrés; Cardin, Julien; Portier, Xavier; Labbé, Christophe; Segura, Camilo; Vargas Cortés, Víctor Alberto; Galdámez Silva, Antonio César; Osorio Román, Igor O. (Royal Society of Chemistry, 2022)
      In this study, we investigate chromium-doped spinels (CDSs) and their characteristic red photoluminescence (PL) due to the strong crystal field and octahedral coordination geometries of the Cr3+ ions. An increase in the ...
