Abstract
Relationship between Physical Properties and Preparation Atmosphere of Manganese-doped ZnO–P2O5 Glasses
Highlights
The physical properties of glass are affected by several factors
We measured the thermal properties of the Manganese-doped zinc phosphate (MnZP) glasses prepared in air and Ar
In the MnZP glasses containing a small amount of Mn cations, Tg decreased with increasing Mn concentration up to 2 mol%
Summary
The physical properties of glass are affected by several factors. In glasses obtained by quenching of the supercooled liquid state, various metastable structures exist to form nonperiodic network structures. The redox state of the glass melt is important for tailoring the physical properties of glasses. Since glass melted in air is inherently affected by the oxygen partial pressure, the physical properties sometimes differ from those prepared in an inert atmosphere.[1,2] The redox state affects the main glass components and the tiny amount of dopants, such as activators. Our group has reported the relationship between the valence state of tin in phosphate and borate glasses and the preparation atmosphere.[3,4,5] It has been clarified that Ce cations doped in borosilicate glasses are strongly affected by the preparation conditions.[6,7,8]
