Determinations of equilibrium segregation, effective segregation and diffusion coefficients for Nd+3 doped in molten YAG

Crystal growth and enhanced magneto-optical properties of a terbium aluminum gallium garnet crystal for Faraday isolators

“…Five specimens of equally spaced positions extracted along the crystal growth direction were measured to evaluate the longitudinal elemental distributions. The concentration of cations at the interface would change with the solidification fractions g by: 20 C s = C 0 × k eff × (1 − g ) k eff −1 where C s is the concentration in the crystal, C 0 is the initial concentration, and k eff is the effective segregation coefficient. Fig.…”

Reporting a novel visible near-infrared {Tb3}[Ga0.1Sc1.9](Al3)O12 single crystal for Faraday isolators

“…The detailed data are summarized in Table S4 (ESI†). The concentration of cations at the interface would change with the solid fraction g by: 36 C s = C 0 × k eff × (1 − g ) k eff −1 where C s is the concentration in the crystal, C 0 is the initial concentration, and k eff is the effective segregation coefficient. The experimental results are summarized into a longitudinal distribution diagram with the change of solid fraction as shown in Fig.…”

Growth, spectra and continuous-wave 2.1 μm laser operation of a Ho3+-doped bismuth silicate crystal

“…The value of the segregation coefficient varies depending on the growth system and conditions, and in particular on the crystallization rate. 22 In Czochralski growth of BGO, the segregation coefficient of Ho 3+ into the BGO crystal was found to be 0.77. 23 Thus, the segregation coefficient can be improved by optimizing the growth process.…”
