“…Antimony oxide based glasses have been the subject of interesting studies in the last years [1][2][3][4][5][6][7][8][9][10][11] and have been claimed to be useful in important fields of the materials science, such as photonics [12][13][14][15][16] and plasmonics [17][18][19] . These materials present low phonon energy (~600-700 cm -1 ) due to low energy stretching vibrations of Sb-O-Sb band 20,21 , high linear and nonlinear refractive indexes [3][4][5] and the possibility of modulation of their optical constants, (refractive index, n, and absorption coefficient, ) under laser irradiation 22 what make them promising materials for 3D optical storage 23,24 as well as, for holographic data storage 25 .…”

(x) , with composition 0.1  x  0.5 (in mol %) were studied. The structural changes due to the replacement of Sb 2 O 3 by WO 3 have been investigated. It was found that the incorporation of WO 3 enhances the thermal stability of the glasses against devitrification when compared to the binary Sb 2 O 3(0.6) -SbPO 4(0.4) composition. The connectivity of the network increases with WO 3 content which is consistent with the high values of the glass transition temperature. Raman studies suggest that WO 3 incorporation breaks the primary network, constituted by antimony oxide, while a second network containing WO 6 octahedral units is built up. Thermal and structural properties were evaluated by differential scanning calorimetry, infrared and Raman spectroscopies, 31 P Magic Angle Spinning NMR and X-ray absorption near edge structure (XANES) at L 1 and L 3 edges of Sb and L 1 edge of W atoms.
