1. Layered Niobates: Synthesis, characterization, reactivity and luminescenece properties study / Niobatos lamelares: síntese, caracterização, reatividade e estudo das propriedades luminescentes
The study described in this Thesis is related to the synthesis and evaluation of some chemical properties of layered niobates with formulas K4Nb6O17 (hexaniobate), KNb3O8 (triniobate) and K1-xLnxCa2-xNb3O10 (layered perovskites - Ln = La, Eu and x = 0.02; 0.25; 0.50; 0.75 and 1.00). These niobates are constituted of negative layers and an interlayer region f

2. Intercalation compounds involving inorganic layered structures
Two-dimensional inorganic networks can shown intracrystalline reactivity, i.e., simple ions, large species as Keggin ions, organic species, coordination compounds or organometallics can be incorporated in the interlayer region. The host-guest interaction usually causes changes in their chemical, catalytic, electronic and optical properties. The isolation of
