Cr2+distribution in ZnSe crystals grown from melt

ZnSe : Cr2+ crystals were grown using a high-pressure vertical zone melting technique with concentrations of 5.1017, 1018, and 1019 cm-3. Infrared transmittance measurements showed a noticeable change in the Cr2+ ions distribution along the as-grown crystals. The effective segregation coefficients of Cr2+ ions were calculated and their dependence on concentration was approximated.
