Solid-state single-crystal growth of YAG and Nd∶ YAG by spark plasma sintering
文献摘要：
Recent studies have shown that many challenges encountered in conventional single crystal growth meth-ods,including high production costs,can be overcome by using the solid-state single-crystal growth(SSCG)approach,which has been recognized as a simple and cost-effective alternative for obtaining sin-gle crystals.In this work,Y3Al5O12(YAG)and Nd3+-doped YAG(Nd∶YAG)single crystals were grown via the SSCG method using spark plasma sintering(SPS).The growth of single crystals was initiated at the surface of(110)YAG single-crystal seeds embedded inside YAG and Nd∶YAG powder beds,and this growth continued as the surrounding polycrystalline matrix was converted into a single crystal.The application of external pressure during the SPS process has been found beneficial for reducing the porosity of the grown single crystals.Moreover,high Nd3+doping levels had a positive effect on the conversion kinetics,with a growth rate of almost 50 pm/h,which increased the driving force for single-crystal growth through the solute drag effect.EDS elemental mapping and line scans confirmed the compositional uniformity of the grown single crystals,while EBSD images verified their crystallization in the(110)direction.The ob-tained results confirm the strong potential of the SSCG technique coupled with SPS for the growth of undoped and highly doped YAG single crystals with excellent quality.
