Growth Twins in YbxY1-xAl3(BO3)4 and NdxGd1-xAl(BO3)4 Crystals Observed by White-Beam Synchrotron Radiation Topography
Growth twins in Ybx Y1-xAl3(BO3)4 (YbYAB) and NdxGd1-xAl3(BO3)4 (NGAB) crystals were observed by white-beam synchrotron radiation topography combined with chemical etch. It was found that growth twins in YbYAB cr...

Influence of Structure on the Formation of Dislocation in LBO Crystal
Dislocations in LiB3O5(LBO) single crystal were investigated by white-beam synchrotron radiation topography(WBSRT). The WBSRT revealed that the grown-in dislocations are mainly pure screw or edge types with the B...
