A Li 2 O–B 2 O 3 –Al 2 O 3 glass system, un-doped and doped with LiF, and/or TiO 2 was synthesized by the fusion method and its physical properties were investigated by thermoluminescence (TL), X-ray diffraction (XRD), electron paramagnetic resonance (EPR), atomic force microscopy (AFM) and differential thermal analysis (DTA). The samples were subjected...
Organic-inorganic hybrids, named di-ureasils and described by polyether-based chains grafted to both ends to a siliceous backbone through urea cross linkages, were used as hosts for incorporation of the well-known coordination complex of trivalent europium (Eu 3+ ) ions described by the formula [Eu(TTA) 3 (H 2 O) 2 ] (where TTA stands for thenoyltrifluoroacetone)...
