For di and trisubstituted- derivatives, dual fluorescence emission was more intense in the derivatives with the amino group in the 4’-position than their analogues with the

However, the spectra obtained using small amounts of the anion did not show any alteration in the position of the signals, which suggests that F − has a very weak interaction

The enhanced optical response of the samples with Ag-NPs is attributed to the growth of the local field on the isolated bismuth ions and clusters that are located in the vicinity

show interesting NIR emission and optical properties for photonic applications, especially as energy converter for improving the efficiency of solar cells, by means of the UV

This observation supports the assumption that host to terbium energy transfer is the cause of this excitation band: indeed, it may be understood that the amine acid strengthens

The differences between the refractive index of the rib channel waveguide and silica optical fibers are crucial to its application as waveguide amplifiers in telecommunication

The emission spectra (Figures 5a and 6a) excited at 275 nm for these samples present similar profiles to those already published in the literature, 1,33,34,36 which describe

According to the results observed in the present study, it is possible to conclude that infrared lasers can chemically alter the microstructure of enamel, dentin and bone; these
