Síntese e estudo das propriedades fotoluminescentes dos pós de CaTiO3 decorados com α-Ag2WO4
(Universidade Federal de São Carlos, 2016-02-24)
The CaTiO3 (CT) and α-
Ag2WO4 (AW) are known to have photoluminescent properties, which is favored by
the existence of a structural disorder. The combination of these two materials was
observed through decoration of ...
