Influence of molybdenum oxide on structural, optical and physical properties of oxychloride glasses for nonlinear optical devices

Abstract

International audienceThe unconventional Heavy Metal Oxide Glasses (HMOG) are characterized by a low phonon energy, large infrared range transmission, high refractive index and nonlinear optical properties. Ternary glasses have been synthesized and studied in the Sb2O3– MoO3-ZnCl2 system. Further, the glass formation compositional limits are reported and some glass samples with the formula: (90-x)Sb2O3 -xMoO3–10 ZnCl2 (10 ≤ x ≤ 50, mole%) were elaborated. Thermal properties have been measured and indicating that the glass transition temperature decreases with increasing proportions of molybdenum oxide. The evolution of density, microhardness and elastic modulus has been studied as functions of parameter x and Raman spectra measurements have been shown the partial conversion of MoO6 octahedral units into MoO4 tetrahedral

Judd-Ofelt analysis and luminescence studies of Er3+ doped halogeno-antimonate glasses

“…Figure 2 shows clearly the monotonic decrease in stability as a function of chemical composition and 80 Sb2O3 -10 ZnBr2 -10 NaCl is the most stable glass. The other physical parameters density, expansion coefficient and elastic moduli have been summarized in Table 1; which are within the limits of antimonate glasses and the corresponding formulas are given by [16], [18], [20]:…”

Dielectric dispersion, linear and nonlinear optical properties of Li2O–WO3–B2O3: V2O5 glasses

“…[1][2][3][4][5][6][7][8] However, most of the studies observed that the nonlinear optical glasses are in general made up of silicate, germinate, chalcogenide and tellurite based glasses doped with metal oxide nanoparticles or rare earth oxides. [1][2][3][4][5][6][7][8] Now, in this work, we explore nonlinear optical properties coupled with dielectric dispersion (polarization) of lithium borate glasses containing two transition metal oxides. Lithium-borate glasses have gained technological importance due to their high transparency for a wide range of wavelengths (200-2500 nm) and low melting point (… 1000 ○ C) compared to that of silicate and germinate glasses.…”

Spectroscopic analysis of up conversion luminescence in doped halogeno-antimonite glass

“…Sb 2 O 3 contributes in the glass network with SbO 3 structural units and it appears tetrahedra with the oxygens to be found at three corners and the lone pair of electrons of antimony Sb 3+ at the fourth corner localized in the third equatorial direction of the Sb atom. There may be a possibility of existence of antimony ions in the Sb 5+ state and participate in the glass network forming with Sb 5+ O 4 structural units may enhance the nonlinear optical properties [48].Antimonite glasses are based on Sb 2 O 3 as a glass former. They belong to the group of HMOG and have been reported in a large number of vitreous systems [37][38][39][40][41][42][43][44][45][46].…”
