摘要：

An optical spectroscopic study of Er-related luminescence in GaAs:Er,O under hydrostatic pressure is reported. The application of pressure results in new Er-related centers becoming optically active under host photoexcitation. Two new sets of I-4(13/2)-->I-4(15/2) transitions are observed to appear in different pressure ranges. It is concluded that these two sets of crystal-field-split transitions are due to the same Er center, and that this Er center undergoes an abrupt change in local configuration ata specific pressure.
