Publikováno v: Journal of Physics and Chemistry of Solids. 61:1535-1542
We present a study of emission, absorption and vibrational properties of Sm3+ doped lead fluoroborate glasses (PbO–PbF2–B2O3–Sm2O3) as a function of the Sm3+ content. Changes in the position and the intensity parameters of the transitions are c

BiO1.5–BO1.5–GeO2 glass system and crystallization of Bi4Ge3O12 phase
Autor: Ronan Lebullenger, Nara C. de Souza, Antônio Carlos Hernandes, M C C Custódio
Publikováno v: Journal of Non-Crystalline Solids. 273:94-99
The BiO 1 5-BO1.5-GeO2 ternary glass samples were prepared by fusion in a platinum crucible and cast in a brass mould. For each nominal composition a sample's physical properties, such as glass transition (T g ), crystallization (T x ) temperatures a

Oxyfluoride glasses containing LiNbO3
Autor: M T Sonoda, Antônio Carlos Hernandes, M C C Custódio, Ronan Lebullenger, André Luiz Martinez
Publikováno v: Journal of Non-Crystalline Solids. 247:35-38
The MoO3–BaF2–NaF–ZnF2–NbO2.5–LiNbO3 and NbO2F–BaF2–LiF–LiNbO3 oxyfluoride glass systems were investigated. Glasses were prepared by fusion at 850°C for 30 min in a platinum crucible and cast in a brass mould at 200°C. For each syst

Publikováno v: ResearcherID
Scopus-Elsevier
Several compositions in the (50 −x) PbO–xPbF2–50B2O3 (0 ≤ x ≤ 20) mol% vitreous system were systematically characterized at room temperature by infrared and Raman microscopic analysis. A general assignment of the vibrations observed for x =
