O presente trabalho tem por objetivo a obtenção de Titanados do tipo C2Ti2O7, MTiO3 e MCTiO3 (M = Chumbo; C= íons metálicos de Terras Raras) a partir do método Pechini desenvolvidos na Universidade Federal do Norte do Tocantins (UFNT) com colaboradores visando agregar conhecimentos multidisciplinares no âmbito da produção de materias cerâmicos nanoestruturados com potenciais aplicação tecnológica. Os pós nanoestruturados de titanatos de Terras Raras (TRT) e de chumbo (PT) puros e dopados com íons metálicos de terras raras, a partir deste método químico, serão utilizados para o entendimento da influência destes dopantes na estrutura, bem como possível utilização, por exemplo, em dispositivos para conversão ascendente (UV-visível) e descendente (IV – visível). A partir da análise por difração de raios X (DRX) e espectroscopia Raman do PT puro e dopado com neodímio, podemos concluir que esses materiais foram obtidos e que o método é adequado para a realização das sínteses dos materiais.
