摘要
A new nonlinear optical (NLO) borate crystal K2Al2B2O7 (Potassium Aluminum Borate, KAB) has been discovered. The structure has been established by 4-axis X-ray diffraction methods. The material crystallizes in the trigonal space group P321 with a = 8.5657(9) Angstrom, C = 8.463(2) Angstrom and Z = 3. KAB possesses a space arrangement similar to Sr2Be2B2O7 (SBBO). A KAB crystal with a dimensions of 30 x 15 x 1 mm(3) was grown using the Top-Seeded Solution Growth (TSSG) method. The optical properties of KAB were measured.
