Abstract High-quality crystals of stoichiometric spinel grown from solution in lead fluoride were subjected to neutron activation analysis to determine rare-earth doping levels. The results have shown that the small rare-earth ion, Er3+, can be incorporated to a small extent, but the larger Nd3+ ion is rejected. Contamination of the crystals with iridium was disclosed. This impurity is derived from iridium in the platinum crucibles used to contain the melts at high temperatures. Iridium contamination may well occur in other crystals grown by the fluxed melt technique. No measurable platinum contamination was found.
