dc.description.abstractZNAL2O4 AND MGAL2O4 THIN FILMS WERE GROWN ON SI(100) AND QUARTZ PLATE SUBSTRATES USING A PHOTOCHEMICAL METHOD IN THE SOLID PHASE WITH THIN FILMS OF BETA-DIKETONATE COMPLEXES AS THE PRECURSORS. THE FILMS WERE DEPOSITED BY SPIN-COATING AND SUBSEQUENTLY PHOTOLYZED AT ROOM TEMPERATURE USING 254 NM UV LIGHT. THE PHOTOLYSIS OF THESE FILMS RESULTS IN THE DEPOSITION OF METAL OXIDE THIN FILMS AND FRAGMENTATION OF THE LIGANDS FROM THE COORDINATION SPHERE OF THE COMPLEXES. THE OBTAINED SAMPLES WERE POST-ANNEALED AT DIFFERENT TEMPERATURES (350?1100 °C) FOR 2 H AND CHARACTERIZED BY FT-INFRARED SPECTROSCOPY, X-RAY DIFFRACTION (XRD), X-RAY PHOTOELECTRON SPECTROSCOPY (XPS), ATOMIC FORCE MISCROSCOPY (AFM), AND UV?VIS SPECTROSCOPY. THE RESULTS INDICATE THE FORMATION OF SPINEL-TYPE STRUCTURES AND OTHER PHASES. THESE CHARACTERISTICS DETERMINED THE QUALITY OF THE FILMS, WHICH WERE OBTAINED FROM THE PHOTODEPOSITION OF TERNARY METAL OXIDES.
