    • Abstract


      Nd3+ : Sr3Ga2Ge4O14 crystals have been grown by the modified Bridgman method. The growth defects, such as striations, scattering particles and dislocations were investigated. Some featherlike striations were observed in as-grown crystals. EPMA analysis suggested that these inclusions were caused by the segregation of Nd2O3 from the melt. Chemical etching results showed that the dislocation density was in the range of 103 ∼ 105/cm2.
