Ea. Krivandina et al., On the variation of the impurity composition in LaF3 crystals grown by theBridgman-Stockbarger method, CRYSTALLO R, 46(4), 2001, pp. 687-689
Single crystals of the composition LaF3 with CeF3, YF3, and SrF2 impurities
have been grown by the Bridgman-Stockbarger method in a graphite crucible
with six cells. The CeF3 concentration has been measured in the LaF3 charge
prior to the growth experiment and in the grown LaF3 crystals upon it. It
is shown that, depending on the growth conditions, the CeF3 Concentration c
an change during crystallization from 25% of its initial concentration in t
he charge up to 550%. (C) 2001 MAIK "Nauka/Interperiodica".
