Oxyfluoride glasses containing Ag species and rare earth (RE) ions (Dy(3+), Sm(3+), Tb(3+)) were prepared by melt-quenching technique. The type of luminescent species of novel excitation band (230-300 nm peaked at 255 nm) and emission band (300-600 n

The novel Ba2Gd2Si4O13:Ce3+,Tb3+ phosphors were systemically investigated by fluorescent method for the first time. Through an efficient energy transfer process, the obtained phosphors exhibit both a blue emission of Ce3+ and a yellowish green emissi

We report the design of an artificial flower-like structure that supports a magnetic plasma in the optical domain. The structure is composed of alternating "petals" of conventional dielectrics (epsilon0) and plasmonic materials (Re(epsilon )0). The i

We propose an efficient method to reduce the crosstalk, reflection and radiation at the crossing of two dielectric waveguides in a on-chip optical interconnect network. By increasing the vertical thickness of the guides locally in the crossing region

Giant positive and negative Goos-Hänchen shift more than 5000 times of the operating wavelength is observed when a beam is totally reflected from a substrate decorated by a dielectric grating. Different to the former studies where Goos-Hänchen shif
