dc.description.abstractWE PROPOSE THE USE OF ALKOXIDE ?-DIKETONATES OF CE(III), ER(III), PR(III) AND YB(III) AS PRECURSORS FOR PHOTOCHEMICAL DEPOSITION OF CEO2:ER AND CEO2:ER/LN (LN = PR OR YB) THIN FILMS, FOLLOWED BY SUBSEQUENT ANNEALING AT 950 °C. THE MEASUREMENTS OF LUMINESCENT PROPERTIES REVEALED THAT CEO2:ER SAMPLES UNDER EXCITATION AT 980 NM EXHIBIT UP-CONVERSION EMISSIONS AT 540 NM AND NEAR INFRARED EMISSIONS CENTERED AT 1550 NM. WHEN CO-DOPING IS PERFORMED ON THE CEO2 FILMS, CEO2:ER/PR REDUCES ITS UP-CONVERSION CHARACTERISTICS AND THE NIR EMISSIONS INCREASE. HOWEVER, THE CEO2:ER/YB SAMPLES SIGNIFICANTLY INCREASE THE UP-CONVERSION PROPERTIES AND INHIBIT NIR EMISSIONS. DIFFERENT MECHANISMS BASED ON ENERGY TRANSFER PROCESSES ARE PROPOSED TO EXPLAIN THESE DIFFERENCES IN THE DEGREE OF INTENSITY OF THESE EMISSIONS.
