Luminescence of Cadmium Fluoride Doped with Rare-earth Ions

GeS2–In2S3–CsI Chalcogenide Glasses Doped with Rare Earth Ions for Near- and Mid-IR Luminescence

Chalcogenide glass has been considered as a promising host for the potential laser gain and amplifier media operating in near- and mid-IR spectral region. In this work, the IR luminescence spectra of rare earth ions (Tm3+, Er3+, and Dy3+) doped 65GeS2-25In2S3-10CsI chalcogenide glasses were measured under the excitation of an 808 nm laser diode. To the best of our knowledge, it firstly provides...

Luminescence and excitation energy transfer in new fluoride crystals containing rare earth ions

Spectroscopic characteristics of Pr3+ and Eu3+ in K2Na2GdF7, K5Li2GdF10 and K3GdF6 fluoride matrices are considered. Crystal structures of these compounds have been ascertained based on X-ray measurement on single crystal samples. Energies of lattice vibrations have been derived from IR and Raman spectra. Spectroscopic features of crystals in the VUV region were studied using experimental facil...

Visible Luminescence of Rare Earth Ions Doped Amorphous Zinc Oxide Thin Films Grown by Sputtering Technique

Preparation and Characterization of Rare Earth Doped Fluoride Nanoparticles

This paper reviews the synthesis, structure and applications of metal fluoride nanoparticles, with particular focus on rare earth (RE) doped fluoride nanoparticles obtained by our research group. Nanoparticles were produced by precipitation methods using the ligand ammonium di-n-octadecyldithiophosphate (ADDP) that allows the growth of shells around a core particle while simultaneously avoiding...

Time-resolved luminescent VUV-spectroscopy of pure and doped by rare earth ions crystals of strontium fluoride

The spectroscopic properties SrF2–Eu(1%), SrF2–Er(1%) and nominal pure SrF2 crystals have been studied using time-resolved vacuum ultraviolet (VUV) spectroscopy under pulsed synchrotron radiation excitation. The 4f24f 5d (f–d) and 4f24f (f f) excitation spectra and emission spectra (with and without of time resolution) have been investigated in the wide energy region at 8 and 295K. Moreover, th...
