原始语种摘要: Abstract(#br)Tellurite-rich glasses containing Sm 3+ , Dy 3+ , and Er 3+ ions with nominal chemical composition of 69 TeO 2 ‒10 Bi 2 O 3 ‒10 BaO‒10 ZnO‒1.0 Sm 2 O 3 /1.0 Dy 2 O 3 /1.0 Er 2 O 3 (mol%) were fabricated. The gamma radiation attenuation features of the synthesized glasses were compared with two other tellurite glass systems with the chemical composition of 68 TeO 2 ‒(22-x) Bi 2 O 3 ‒10 ZnO‒ (x) PbO (x = 10, 12, 14, 16 and 18 mol%), and 75 TeO 2 ‒20 B 2 O 3 ‒5 M x O y (mol%) (M x O y = WO 3 , Nb 2 O 5 , PbO, Nd 2 O 3 , Y 2 O 3 ). The mass attenuation coefficients (μ/ρ) (MAC) were computed from 0.015 MeV to 15 MeV photon energies using the XCOM program. Using the obtained μ/ρ values, effective atomic number (Z eff ), electron density (N e ), half-value layer (HVL) and mean free...
