High pressure effect on optical properties of cerium ion in fluoroaluminate glass

Time-resolved luminescence study of CaF2:Eu2+ nanocrystals in glass-ceramics

“…By using the liner expansion coefficients of CaF 2 and glass-ceramic and the Young's modulus of CaF 2 [4,7], we can estimate the magnitude of the dilatational strain to be ARTICLE IN PRESS 5À10 GPa on the assumption that a spherical CaF 2 crystal is embedded in the glass-ceramic. This seems consistent with the result of Ce 3+ -doped fluoroaluminate glasses [8], in which the luminescence peak due to the 5d-4f transition of Ce 3+ ions is low-energy shifted by 0.03 eV under compressive pressure of 2 GPa.…”

Preparation and optical properties of CeF3-containing oxide fluoride glasses

“…In those studies, the control of the valence of cerium ion is important to control the optical properties of the glasses. Especially, the Ce 3+ content is related directly to the performance of the compounds as scintillation counter materials, phosphors, and LED materials [8,[11][12][13]. Radiation emission of Ce 3+ causes the transitions between the 4f and 5d electronic states.…”

ZnF2‐modified AlF3‐based fluoride glasses with enhanced mid‐infrared 3.5 μ$\umu$m emission

“…11,12 In recent years, several fluoroaluminate glasses with stable chemical and thermal stabilities have been developed to realize mid-infrared fiber lasers. A typical glass system is AlF 3 -YF 3 -MF 2 (M = Ba, Pb, Mg, Ca), 13,14 which has a phonon energy of about 650 cm −1 . Based on this glass system, low-loss fluoroaluminate glass fibers can be fabricated and used for implementing ∼3 μm fiber lasers.…”
