Structure and chemical property studies of some vanadium boro-phosphate glasses containing iron

Thermoluminescence features of alumina‐mixed borophosphate glasses with Tb3+ ions for dosimetric applications

“…For this reason, induced defects due to gamma-ray irradiation will last longer in the bulk material, and as a result, the fading effect of TL emission with time will be reduced. 13 The TL emission of the material also depends on the relative content of Tb ions in different coordinations (6)(7)(8)(9)(10)(11)(12) and their valence states. Al 3+ ions participate in the glass network with AlO 4 and AlO 6 structural units.…”

“…However, due to its low hygroscopic resistance, various other glasses, containing low fractions of TL activating ions, are being considered for such applications. [1][2][3][4][5] Borophosphate glasses are relatively more moistureresistant (due to the presence of strong B-O-P linkages between BO 4 and PO 4 structural units [6][7][8] ) when compared with individual borate or phosphate glasses. For this reason, induced defects due to gamma-ray irradiation will last longer in the bulk material, and as a result, the fading effect of TL emission with time will be reduced.…”

“…However, non-Kramers Tb 3+ ion is EPR-silent as it possesses an even number of 4f electrons. 13 The TL emission of the material also depends on the relative content of Tb ions in different coordinations (6)(7)(8)(9)(10)(11)(12) and their valence states. Further, by varying the concentration of Al 2 O 3 in borophosphate glass network, one can expect interesting environmental variations around the Tb 3+ ions embedded in the glass network; such variations influence the thermoluminescence output and dose response.…”

Optical and structural characterization of quadruplet and quintuplet molybdenum-containing phosphate glasses

“…2 In fact, P O bonds in pure phosphate glass structures can interact with moisture and form phosphoric acid which cause a decrement in the stability of samples. 3,4 In order to solve this problem, various modifying metal oxides have been incorporated into the glass system to control the degradability and it can be further durable using transition metals. These specimens can create stronger ionic bonding with phosphate chains.…”

“…13,14 In the recent years, the spectroscopic analysis has been widely used in order to study the structural properties of phosphate glasses containing TMOs and alkali oxides. 3,10,[15][16][17][18][19][20][21] Moreover, optical analysis is one of the most effective methods in interpretation and extension of electronic structure theory in amorphous and crystalline solids. The presence of molybdenum ions in glasses yields to some interesting variable optical properties depending on the type and composition of glasses.…”
