“…TL studies are reported in impurity doped mixed metal borates such as SrMg(BO 3 ) 2 [5], LiBa 2 B 5 O 10 :RE 3 þ [6], LiSr 4 (BO 3 ) 3 :Ce [7], LiKB 4 O 7 [8], KSr(BO 3 ) 3 :Ce [9], NaSr(BO 3 ) 3 : Ce [10], LiSrBO 3 :RE 3 þ [11], and LiCaBO 3 [12][13][14]. Wu et al [15] prepared lithium-magnesium borate compounds and determined its structure.…”
