Li2O-K2O-B2O3-PbO glass system: Optical and gamma-ray shielding investigations

Enhancement of Gamma-ray Shielding Properties in Cobalt-Doped Heavy Metal Borate Glasses: The Role of Lanthanum Oxide Reinforcement

“…Another significant parameter in the radiation shielding field is the tenth value layer (TVL), which is the material thickness needed to attenuate 10% of the initial incident gamma-ray intensity. As shown in Table 2, the half value layer (T1/2) values of the investigated S5 samples were compared with those of Glass1 (Cr2O3-doped BS glass) [40], Glass2 (obsidian glass doped with CeO2) [41], Glass3 (BaO-TiO2-SiO2-B2O3 glass) [42], Glass4 (Li2O-K2O-B2O3-PbO glass) [43], Glass5 (Li2O-K2O-B2O3-HMO (HMO = SrO/TeO2/PbO/Bi2O3)) [44], Glass6 (xBaO-(0.30-x) MgO-0.10Na2O-0.10Al2O3-0.50B2O3 glass) [45], and standard shielding materials (ordinary concrete: OC [46], and hematite-serpentine concrete: HSC [47]); the T1/2 values of the S5 samples were lower than those of all other samples, even OC and HSC. As shown in Table 2, the half value layer (T 1/2 ) values of the investigated S5 samples were compared with those of Glass1 (Cr 2 O 3 -doped BS glass) [40], Glass2 (obsidian glass doped with CeO 2 ) [41], Glass3 (BaO-TiO 2 -SiO 2 -B 2 O 3 glass) [42], Glass4 (Li 2 O-K 2 O-B 2 O 3 -PbO glass) [43], Glass5 (Li 2 O-K 2 O-B 2 O 3 -HMO (HMO = SrO/TeO 2 /PbO/Bi 2 O 3 )) [44], Glass6 (xBaO-(0.30-x) MgO-0.10Na 2 O-0.10Al 2 O 3 -0.50B 2 O 3 glass) [45], and standard shielding materials (ordinary concrete: OC [46], and hematite-serpentine concrete: HSC [47]); the T 1/2 values of the S5 samples were lower than those of all other samples, even OC and HSC.…”

Influence of barium substitution on the physical, thermal, optical and luminescence properties of Sm3+-doped metaphosphate glasses for reddish orange light applications

“…Nowadays, optical materials based on trivalent lanthanide ions are being widely applied in various technological applications such as photonic displays, communications devices, laser materials, hole burning high-density memories, optical storage, etc. [1][2][3][4][5][6] Therefore, the special features of glassy matrices, such as low production cost, better thermal stability, mechanical strength, and chemical durability, make them more suitable as host materials than crystalline compounds. Phosphate-based glasses are recognized as signicant materials in certain applications due to their favorable characteristics, including high solubility for rare-earth ions with minimal clustering effects, low melting temperature, low glass transition temperature, high thermal expansion coefficient, and biocompatibility.…”

Radiation shielding ability and optical features of La2O3+TiO2+Nb2O5+WO3+X2O3 (X=B, Ga, and In) glass system containing high-entropy oxides

“…This is important in a mixed radiation field or in situations where the interaction of one form of radiation can give birth to another, such as in the radiative capture of neutrons. Therefore, composite materials, including glasses, rocks, and alloys, have been actively researched and recommended for radiation shielding in different radiation application scenarios [ [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] , [36] ]. Some of these materials have shown great potential as radiation shields; others have possessed certain qualities that make them preferable in different shielding scenarios.…”
