“…Incorporating rare earth in silver halide crystals and fibers may induce amplification and lasing in mid-IR. All experiments and calculations indicate that these doped crystals and fibers would be good candidates for the fabrication of mid-IR solid-state lasers or fiber lasers [1][2][3][4][5][6][7].…”

“…The luminescence of AgCl, AgBr and AgCl x Br 1-x crystals and fibers doped with lanthanide ions Ln 3? was investigated because of the potential use as solid-state lasers that operate in the middle-infrared spectral range [1][2][3][4][5][6][7]. These materials are highly transparent in the near-and mid-IR ranges and have desirable mechanical and optical properties.…”

Differential thermal analysis and differential scanning calorimetry were used to investigate phase equilibria in the AgCl-LnCl 3 (Ln = Ce, Sm, Gd) binary systems. It was found that systems under investigation represent typical examples of simple eutectic systems. The eutectic compositions and eutectic temperatures were found to be: x(CeCl 3) = 0.095, T eut-= 700 K (for AgCl-CeCl 3), x(SmCl 3) = 0.228, T eut = 644 K (for AgCl-SmCl 3) and x(GdCl 3) = 0.288, T eut = 609 K (for AgCl-GdCl 3). The thermodynamic functions of mixing in AgCl-LnCl 3 systems (Ln = Ce, Nd, Sm, Gd) were predicted on the basis of experimental data using the CALPHAD method by association model (AM) and Redlich-Kister model (RKM). The possibility of existence of the associates in the liquid phase was discussed.

“…These properties allow the use of these fibers in medical applications, 3,4 bioanalytical applications, 5,6 optical sensing applications, and others. [7][8][9] Although the number of reflections inside the silver halide fibers is large enough to provide sensitivity in detection, an enrichment technique is generally required. This is commonly accomplished by applying a hydrophobic material to the fiber surfaces to attract target analytes into the evanescent field.…”

Chemical Reduction Method for Preparation of Silver Nanoparticles on a Silver Chloride Substrate for Application in Surface-Enhanced Infrared Optical Sensors

2010

A new method for the preparation of silver nanoparticles (AgNPs) on silver chloride discs was developed to integrate the unique properties of plasmonic nanoparticles into infrared optical sensing technologies. AgNP layers exhibiting strong infrared surface enhancement were prepared by reacting silver chloride discs in a solution containing hydrazine, which acts as a reducing agent. The silver ions in the outer layer of the disc could be reduced under proper conditions and the reduced silver coagulated to form suitable AgNPs for surface-enhanced infrared absorption (SEIRA) measurements. To examine the influences of the reaction solution composition and also to optimize preparation of SEIRA substrates, factors such as pH value, reaction time, and concentration of reducing agent were examined. Results indicated that both the concentrations of hydrazine and hydroxide strongly influenced the SEIRA signals. The strongest signals were observed when AgNPs on a AgCl substrate were prepared by using a reducing solution of 20 mM NaOH with 0.75 mM hydrazine. Using the optimized substrates, intense SEIRA spectra were observed with an enhancement factor around two orders of magnitude compared to measurements made using conventional sampling techniques.

“…The high ionic conductivity of some solid silver halide phases makes them good candidates for a number of technological applications such as solid electrolytes in electrochemical power systems [1] or solid-state lasers that operate in the middle-infrared spectral range [2][3][4][5][6][7][8]. The luminescence of AgBr, AgCl, and AgCl x Br 1−x crystals and fibers doped with several lanthanide Ln 3+ ions was investigated in the middle-infrared range [2][3][4][5][6][7][8].…”
