EPR and IR studies on the local structure of 80MoO3–20B2O3 glass

Structure of TeO2·B2O3 glasses inferred from infrared spectroscopy and DFT calculations

“…Some exceptions to this rule are known, the two-component TeO 2 [1], MoO 3 [2] or WO 3 [3] glasses, in which these cations are assigned a co-ordination number of six. For tellurium, Brady [4] suggested, on the basis of an X-ray diffraction study of lithium tellurate glasses, that the addition of a modifying oxide necessary for glass formation reduces the fraction of octahedral which share edges, thus reducing the rigidity of the structure and making it easier to produce disorder.…”

Dielectric dispersion in Li2O–MoO3–B2O3 glass system doped with V2O5

“…Further, Mo O bond in molybdenum hexavalent oxide is identified as significantly covalent [8,9]. A quite good number of recent studies on various physical properties viz., spectroscopic, DC conductivity, dielectric properties, etc., of a variety of glass systems containing molybdenum ions are available in literature [10][11][12][13][14][15][16][17]. Semiconducting transition metal oxide glasses have gained importance in recent years due to their possible applications in various technological fields [18][19][20][21].…”

EPR and Optical Studies of Mo5+ Ions in Lithium Molybdoborate Glasses

“…Since the coordination number of molybdenum is six, we can consider that MoO 3 [17]. The structure of molybdoborate glasses may therefore be considered as generated from the corners-shared triangular and octahedral units as shown in Fig.…”

“…to a Mo 6! site and as a result, the glasses containing MoO 3 are ntype semiconductors [3]. Lithium boromolybdate glasses may be used as positive electrodes in solid-state batteries, their electrical conductivity being mainly due to both the high mobility of the lithium ion and electron semiconduction due to the electron transfer, or hopping of unpaired electrons from the paramagnetic Mo 5!…”
