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

An extra-cavity pulse generation by thermocavitation in a Hibiscus sabdariffa L. extract (a natural anthocyanin) is presented. This is, to the best of our knowledge, the first experimental demonstration of thermocavitation in a natural extract. It is

Z-scan technique offers simplicity to determine nonlinear optical properties. We propose its use in nanoparticles of TiO2 functionalized with an azo-triphenylmethane dye obtaining n2=3.37×10−3 and β=1.28×105 which allows us to propose them for s

A macro-porous silica film served as mechanical support to immobilize TiO2 nanoparticles, which were doped with erbium. The films and the nanoparticles were prepared by sol–gel route. The nanoparticles exhibited photocatalytic activity under visibl

The intensity of erbium up-conversion luminescence could be limited by a saturation effect due to increased pump power. We studied the luminescence saturation of the 550 nm emission on erbium-doped, SiO2–TiO2 sol–gel powders under pulsed excitati
