dc.description.abstractIN THIS STUDY WE REPORT SIGNIFICANT ENHANCEMENT OF UP-CONVERSION EMISSIONS OF LA2O3:ER THIN FILMS WHEN THEY ARE CO-DOPED WITH ER/LN (WHERE LN = ND OR HO). THE PROPOSED MECHANISMS BY WHICH THE LN IONS CONTRIBUTE TO THESE EMISSIONS ARE BASED ON DIFFERENT MECHANISTIC ROUTES. WHILE THE LA2O3 SAMPLES CO-DOPED WITH ER/ND INVOLVES ENERGY TRANSFER NDIII?ERIII PROCESSES, IN THE LA2O3 SAMPLES CO-DOPED WITH ER/HO INVOLVES ENERGY TRANSFER ERIII?HOIII PROCESSES. ALL SAMPLES WERE SYNTHESIZED BY A SOLID STATE PHOTOCHEMICAL DEPOSITION METHOD FOLLOWED BY A SUBSEQUENT CALCINATION PROCESS. THE LUMINESCENT PROPERTIES REVEAL THAT SAMPLES UNDER 980 NM IRRADIATION EXHIBIT CHARACTERISTIC UP-CONVERSION EMISSIONS THAT ARE FOCUSED IN THE GREEN REGION OF THE SPECTRUM AND THAT THE NATURE OF SECOND ACTIVATOR (LN) DETERMINES THE DEGREE OF EFFICIENCY OF THESE EMISSIONS.
