xR2O3–(100 − x)Al2O3 binary glasses (R = Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) were synthesized by containerless processing using an aerodynamic levitation furnace. Transparent glasses with a composition of x = 30 and 32 were

While the phenomena of phase separation in bulk glass have been well examined, those of amorphous thin films have not been fully detailed. From the viewpoint of new applications, the control of phase separation in thin films is very interesting. To i

Structural models of a single component vitreous state were systematically developed using molecular dynamics simulations incorporating ionic pair potentials. The M–X (M is a cation and X is an anion) pair bond distance was constrained between 1.4

The energy transfer rate between Tm3+ ions in ZBLAN glass was estimated from the optical spectra and transition rates on the basis of a method proposed by Kushida. The optical spectra and radiative transition rates were obtained from the structural m

Absorption and emission spectra of a Tm 3+ -doped glass based on AlF 3 were estimated from crystal-field parameters based on crystal-field theory and Judd–Ofelt theory. On the basis of point charge approximation, two kinds of crystal-field paramete

Absorption and emission spectra of Pr 3+ -doped ZBLAN glass at room temperature were estimated from even- and odd-parity components of crystal-field parameters based on crystal-field theory and Judd–Ofelt theory. On the basis of point-charge approx

New fluoride glasses were developed in the SnF2–PbF2–ZnF2 system. Additions of 5 mol% of CsCl or 6–15 mol% of AlF3 were found to stabilize the glass formation. The IR absorption of the glasses and the optical properties of the europium ions dop

Europium doped fluorozirconate and chloro-fluorozirconate glasses with Zr–Ba–La–Al–F–Cl system were prepared by conventional melting method and their emission spectra were studied. Simulation of emission spectra of these glasses by point ch
