Alberth de Figueiredo

Graduado(a) em: Química
Último(a) Orientador(a) no INCTMN/CMDMC: José Arana Varela  
Laboratório: INCTMN - UFG    
Início no INCTMN/CMDMC:
2004
Resumo de Trabalho:
 
Estudos estão sendo deenvolvidos na área de luminescência de nanofósforos inorgânicos dopados e co-dopados com íons terras-raras. A matriz escolhida é o CaTiO3, e os dopantes e co-dopantes serão os íons lantanídeos: Sm3+, Pr3+ e Eu3+. A co-dopagem justifica-se no fato de que existem vários estudos mostrando que com a superposição espectral das bandas de emissão de um dos íons com a banda de absorção do outro íon pode ocorrer um eficiente mecanismo de transferência.
