Synthesis and electrical properties of Fe2O3-MoO3-TeO2 glasses

Optical absorption, fluorescence and thermoluminescence properties of ZnF2–MO–, CdO and PbO) glasses doped with Er3+ ions

“…Further, these glasses are considered very good materials for hosting lasing rare-earth ions since they provide a low phonon energy environment to minimize non-radiative losses. A number of recent investigations on mechanical, electrical and optical properties of various tellurite glasses mixed with different modifiers are available in the literature [1][2][3][4][5][6][7][8]. A considerable number of these studies on various physical properties have also been reported in the recent past from our laboratory on some TeO 2 -based glass systems [9][10][11][12][13][14].…”

Electric conductivity of glasses in the system Na2O/CaO/SiO2/Fe2O3

“…a tunneling probability e À2aR ¼ 1 is possible. This has already been shown to be invalid for similar iron containing systems within the studied temperature interval [10][11][12][13][14][15]22,25,26]. In fact, the calculations carried out for the sub-system 16Na 2 O AE 10CaO AE (74 À y)SiO 2 AE yFe 2 O 3Àd show that the tunneling probability for this set of compositions is e À2aR $ 10 À9 -10 À6 , i.e.…”

“…The distances between the iron ions were calculated from the composition and the respective density, assuming a random distribution of the iron ions in the glass [21,22,25,26]. The values are summarized in Table 2, column 4.…”

“…The conductivity of phosphate, borate, vanadate and tellurite glasses and also of ternary silicate glasses containing transition metal ions has frequently been reported in the literature [10,[12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27]. Besides, the conductivity of glasses and glassy materials from the system PbO/SiO 2 / Fe 2 O 3 was studied [15].…”

FTIR, Raman, and UV-Vis spectroscopic and DFT investigations of the structure of iron–lead–tellurate glasses

“…Oxide glasses including transition metal ions were extensively studied due to their semiconducting properties [1][2][3][4][5][6]. The conduction in ternary iron oxide glasses was confirmed to be due to hopping conduction of polaron [7].…”
