A facile method is reported to synthesize macroporous silica films embedding rhodamine 6G. The films were obtained by sol-gel and spin-coating processes. Results pointed out a dependence of pore formation on the addition of rhodamine 6G in the film c

Spectroscopic properties of erbium ions in SiO 2 -TiO 2 -Er 3+ powders are studied and the nature of the emissions discussed. A strong green luminescence and less intense red and blue emissions were observed in the samples when exciting at 490 nm, 53

A polymer system is studied (a PMMA + MMA + TEGDMA blend) whose free volume properties are determinant for the process of blending and packaging of polymer chains. In this case a possible influence of the Flory-Huggins interaction parameter on the fr
