Treball Final de Grau en Química. Codi: QU0943. Curs acadèmic: 2019/2020Pyrochlores are widely studied for their variety of properties according to their
composition, hence their versatility. In this bibliographic work, the study of nanopigments with pyrochlore structure with luminescent properties is shown. It focuses on
a wide range of theoretically based introductions of pigments, pyrochlore structure and
luminescence. Specifically, Eu 3+ doped Gd2Ti2O7 is studied, comparing three methods
of synthesis: sol-gel, Pechini and solid state. Finally, the experimental results are
proposed through the application of X-Ray diffraction (XRD),
Thermogravimetry/Differential Thermal Analysis (TG/DTA), Scanning Electron
Microscopy (SEM) and Photoluminescence spectrocopy. Detailed description of each
procedure step and discussion of the obtained results have been performed along the
project.
Additionally, a bibliographic search and description of main theoretical concept on
pigments, together with analysis of State of art of inorganic pigments have been
performed. Some possible application of the developed materials is proposed
