“…The strong evidence to support this observation is that no shift in the TL peak with dose in a wide dynamic range is observed [28]. Hunda et al [16] also support first order kinetics for the main dosimetric peak of LTB:Cu single crystals. The TL sensitivity of the LTB:Cu single crystal has been compared with those of some of the popular TL phosphors like TLD-100, TLD-500 and TLD-900.…”

“…It is reported that single crystals show higher TL intensity, thermal stability and low hygroscopicity as compared with polycrystalline materials [14][15][16]. Shahare et al [17] also showed that crystalline LTB:Cu has good TL sensitivity compared with glassy LTB.…”

“…On the basis of computer modeling Hunda et al [16] also mentioned first order kinetics for the high temperature peak of LTB:Cu at 228 1C. Prokic [4] (sintered LTB:Cu, In pellets) and Huy et al [23] (LTB:Cu single crystals using Bridgeman technique) reported non-first order kinetics for the LTB:Cu phosphors whereas Manam and Sharma [27] (polycrystalline LTB:Cu powder) have reported second order kinetics for the main TL peak at 175 1C.…”

“…On the other hand, our results demonstrate that the TL and roentgenoluminescence (RL) of polycrystalline LTB-based samples depend significantly on their stoichiometry (excess B 2 O 3 increases TL intensity and reduces RL intensity) [15,16] [20,21]. For this reason, to obtain highquality LTB crystals the growth charge must be slightly enriched in boron oxide [21,22].…”

Li 2 B 4 O 7 (LTB) single crystals are grown from stoichiometric and B 2 O 3 -enriched (1.6 and 2.4 mol %) melts. At large B 2 O 3 excesses, the thermoluminescence intensity in the crystals is markedly higher, attesting to an increased density of structural defects. LTB crystals grown from B 2 O 3 -enriched melts may contain zones enriched in two types of defects. Defects of one type result from the breaking of bonds involving bridging oxygens, without significant changes in the position of neighboring atoms. Defects of the other type appear at large B 2 O 3 excesses in the melt, which enable more significant changes in the structure of the boronoxygen framework, leading to the formation of nanoscale regions differing in composition from LTB. The present results may be helpful in assessing the quality of LTB single crystals and in optimizing the crystal growth of LTB.

“…Rare earth doped borate materials have found application in Plasma Display Panels as red emitting phosphor ((Y,Gd)BO 3 :Eu), UV emitting medical lamps (SrB 4 O 7 :Eu), as green-emitting phosphor in fluorescent lamps (GdMgB 5 O 10 :Ce, Tb) [7]. For dosimetric application, alkali borates (Li, K) and magnesium borates have been extensively investigated [8][9][10][11][12][13]. Strontium tetraborate, SrB 4 O 7 , has a unique structural framework consisting of a three-dimensional (B 4 O 7 ) network of BO 4 tetrahedra, with Sr 2+ cations participating in SrO 9 polyhedra [14][15][16][17].…”
