In the present paper we report the optical response of an ordered array of silver (Ag) nanoparticles (NPs) using the uniaxial L i N b O 3 as a model case. We investigate the anisotropic effects on the effective dielectric tensor taking into account t

We report optical absorption and luminescence measurements in pure and trivalent neodymium (Nd3+) doped LaVO4 crystals up to 25 GPa. Nd3+ luminescence has been employed as a tool to follow the structural changes in the crystal. We also present band-s

La3NbO7 compounds doped with Er3+ were synthesized by conventional solid state reaction. X-ray diffraction (XRD) and scanning microscopy (SEM-EDS) were used to analyze the morphology and microstructure of this ceramic powder. Rietveld's refinements s

A detailed study of the optical spectroscopy of Er3+ in Ca3Ga2Ge3O12 crystals is reported. Several site selective techniques were employed (absorption, luminescence, excitation and up-conversion). The combined use of these techniques allowed the sepa

Thermochemical reduction (TCR) at 2173K has been performed on nominally pure yttria-stabilized zirconia crystals. After TCR the crystals become opaque owing to a very intense optical absorption band centred at 2.64eV. Analytical transmission electron
