| dc.description.abstract | Y2O3 THIN FILMS DOPED WITH DIFFERENT CONCENTRATIONS OF ERBIUM IONS AND CO-DOPED WITH 10 MOL% OF YTTERBIUM WERE SYNTHESIZED BY A SOLID STATE PHOTOCHEMICAL DEPOSITION METHOD FOLLOWED BY A SUBSEQUENT CALCINATION PROCESS. THE PHOTO-REACTIVITY OF THE THIN FILMS WAS MONITORED BY FOURIER TRANSFORM INFRARED (FT-IR) SPECTROSCOPY. XRAY DIFFRACTION (XRD), X-RAY PHOTOELECTRON SPECTROSCOPY (XPS), SCANNING ELECTRON MICROSCOPY (SEM), UV-VIS SPECTROSCOPY AND PHOTO-LUMINESCENCE (PL) WERE EMPLOYED TO CHARACTERIZE THE SAMPLES. THE RESULTS REVEAL THAT Y2O3:ER FILMS UNDER 980 NM IRRADIATION EXHIBIT CHARACTERISTIC UP-CONVERSION EMISSIONS THAT ARE FOCUSED IN THE GREEN REGION OF THE SPECTRUM; THESE EMISSIONS ARE ASSIGNED TO THE (H-2(11/2), S-4(3/2)) -> I-4(15/2) TRANSITIONS OF THE ER3+ IONS. THESE EMISSIONS GREATLY INCREASE IN INTENSITY WITH THE ADDITION OF YB3+ IONS IN THE PREPARATION OF THE CODOPED FILMS. THIS PHENOMENON IS EXPLAINED BASED ON THE EFFICIENT YB3+ -> ER3+ ENERGY TRANSFER PROCESSES. | |
