| Abstract: | Cerium‐doped lithium gadolinium borate (Li6Gd(BO3)3:Ce) single crystal has been grown by the Czochralski method. Some problems like macro defects and concave growth face were found. The macro defects are suggested to be caused by constitutional supercooling and concave growth face is caused by interface inversion. These problems can be resolved or eliminated through controlling the growth parameters strictly. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
