Preparation and luminescence of new Nd3+ doped chloro-sulphide Glass-ceramics
Optical Materials, 2017Co-Authors: Vincent Seznec, Hongli Ma, Xvsheng Qiao, Virginie Nazabal, Jean-luc Adam, Xianghua Zhang, Xianping FanAbstract:Chalcogenide Glass-ceramics containing rare earth have been studied. A reproducible process has been established for making transparent Glass-ceramics. The presence of micro-crystals inside the chalco-Halide Glass-ceramics induces scattering at the short wavelengths. Photoluminescence of rare earth has been greatly increased in Glass-ceramics. To our best knowledge, this is the first paper on rare-earth-doped Glass-ceramics based on chalcogenide.

Spectroscopic properties of Er3+-doped chalco-Halide Glass ceramics
Optical Components and Materials III, 2006Co-Authors: Vincent Seznec, Xvsheng Qiao, Virginie Nazabal, Jean-luc Adam, Xianghua Zhang, Xianping FanAbstract:In this paper, we present results concerning the fabrication and characterization of Glass-ceramics based on chalcoHalide for application as laser host materials. The objective is to develop a highly efficient host material for rare-earth doping. The studied system is Ga-Ge-S-CsCl with Er 3+ ions as doping elements. Glass-ceramics have been prepared by thermal treatment of the base Glass. The evolution of the optical transmission versus annealing time and temperature has been investigated. Preliminary up-conversion measurement of Er 3+ were performed. Glass ceramics show higher luminescence efficiency as compared to the base Glass. Nano-crystalline phases have been generated in well-controlled experimental conditions, so that crystals with reproducible size smaller than 50 nm could be achieved.

Tellurium Halide Glass fibers: preparation and applications
Journal of Non-crystalline Solids, 1995Co-Authors: Chantal Blanchetiere, K Le Foulgoc, H.l. Ma, Xianghua Zhang, Jacques LucasAbstract:Abstract Tellurium Halide (TeX) Glasses were prepared from high-purity raw materials which were purified in a silica set-up in order to eliminate the surface oxides. All the starting elements were then distilled. The rod in tube method was used to obtain TeX Glass fibers having a core-cladding structure. The fiber attenuation was measured by using a Fourier-transform infrared (FTIR) spectrometer. The fiber losses, regularly obtained, were

Tellurium Halide Glass fibers: preparation and applications
Journal of Non-Crystalline Solids, 1995Co-Authors: Chantal Blanchetiere, K Le Foulgoc, Xianghua Zhang, Jacques LucasAbstract:Tellurium Halide (TeX) Glasses were prepared from high-purity raw materials which were purified in a silica set-up in order to eliminate the surface oxides. All the starting elements were then distilled. The rod in tube method was used to obtain TeX Glass fibers having a core-cladding structure. The fiber attenuation was measured by using a Fourier-transform infrared (FTIR) spectrometer. The fiber losses, regularly obtained, were < 1 dB/m in the 5–9 μm range for mono-index fibers and about 1 dB/m for core-clad fibers. CO2 laser power delivery has been performed using a TeX Glass fiber. More than 2.6 W has been obtained through a 1 m long fiber. These fibers have a wide optical window and were used in remote spectroscopy to analyze chemical species which absorb between 3 and 13 μm. Different fermentation processes were monitored by this method which allows a quantitative and qualitative analysis after calibration of the system. Potential applications are discussed.
