Abstract

PURPOSE: To provide a clear pinck artificial jewel by substituting Er for part of Gd in a gadolinium gallium garnet (GGG) single crystal without deteriorating the characteristics of GGG.
CONSTITUTION: High purity powders of Gd2O3, Ga2O3 and Er2O3 are charged into a crucible made of Ir or the like in a predetermined ratio, and they are heat melted. A single crystal of the formula is then formed from the melt by a pulling method, a temp. gradient method, the Verneuil method or other method. Er is substd. for 1W5, pref. 3W5mol% of Gd in a GGG single crystal. The resulting single crystal may be cut and polished to give a pink or red jewelly material.
