Mixed transition and rare earth ion doped borate glass: structural, optical and thermoluminescence study

Effect of Y3+ on the structural and photoluminescence properties of yttrium‐doped sodium borate glass

“…[ 17 ] A broad band appeared at 962 cm −1 and shifted to 924 cm −1 with the increase in the Y 2 O 3 concentration in the glass, related to the vibration of the tetrahedral BO 4 stretching units. [ 18 ] Another broad band at ~867 cm −1 could be attributed to the asymmetric stretching vibration of tetrahedral borate BO 4− units. [ 11 ] It seems that excess Y ions prefer to inhabit the modifier positions after occupying all the allowed places in the former positions, especially for higher Y 2 O 3 content samples.…”

“…[ 22 ] Two bands at 832–894 cm −1 and 1035–1083 cm −1 were caused by tetrahedral BO 4 unit B–O bond stretching. [ 18 ] In the range 1118–1153 cm −1 , there was asymmetrical stretching of the B–O bond of trigonal BO 3 units with NBOs. [ 23 ] The trigonal BO 3 units caused asymmetric stretching relaxation of the B–O bond at ~1518–1551 cm −1 .…”

Scintillation Properties of Dy-doped 50NaPO3–50Al(PO3)3 Glasses

“…To detect ionizing radiation efficiently, the use of bulk materials is essential since the probability of an interaction between ionizing radiation and a detector material simply depends on the volume of the material. To satisfy this requirement, bulk single crystals, (9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19) ceramics, (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30)(31) and glasses (32)(33)(34)(35)(36)(37)(38) have been applied for scintillators and dosimeters. Among these material forms, glasses have some advantages such as high chemical durability and high light transmittance, which are preferable for scintillator and dosimeter uses.…”

Absorption Spectra Comparison of Tm/Ho-Codoped Bototellurite Glasses

“…Boron Oxide (B2O3) is a glass former meaning that it can form a glass by itself or there is no requirement that other materials need to be added. Borate glass is characterised by its low phonon energy, which normally in the range of 1300-1500 cm -1 , low melting point, high transparency, high chemical resistance, good thermal stability, homogeneity, relatively low melting point, and good solubility of rare-earth ions ((Mahraz et al, 2013, Bhatia et al, 2018Rajagukguk et al, 2019;Yang et al, 2008). On the other hand, telluriumoxide (TeO2) is a conditional glass former.…”
