The K3Y3（BO3）4 can be an excellent host for doping of Yb3＋, because there are six low-symmetric yttrium atoms in one unit-cell of K3Y3（B 03）4. The growth of K3Y3（BO3）4 was studied in detail, and a good crystal with sizes of 24 mm × 15 mm× 8 mm was grown successfully below 900 ℃. Some characteristics, such as the X-ray dif- fraction, infrared spectroscopy, and thermal analysis, were also performed.展开更多
