Synthesis and Characterization of TiO2 Nanocrystals Prepared from n-Octadecylamine−Titanyl Oxalate Langmuir−Blodgett Films

摘要: TiO2 nanosized clusters have been prepared by the Langmuir−Blodgett technique starting from n-octadecylamine−titanyl oxalate complex. The floating film morphology has also investigated Brewster angle microscopy (BAM). presence of in subphase promotes formation aggregates n-octadecylamine on surface. LB films initially contain embedded organic amorphous matrix; their structural evolution induced thermal annealing investigated. UV−vis spectroscopy, high-resolution transmission electron (HRTEM), and small area diffraction (SAD) characterization methods are used as synergic techniques giving complementary information regarding both features photophysical properties.
