Guangyuan Qu, Zhifang Hu, Yipei Wang, Qing Yang and Limin Tong Synthesis of Optical-Quality Single-Crystal β-BaB2O4 Microwires and Nanowires Advanced Functional Materials 23
Optical-quality single-crystal β-BaB2O4 microwires and nanowires (MNWs) are synthesized in an organic-free hydrothermal method assisted with post-annealing at 700 °C. As-synthesized MNWs have excellent diameter uniformity and surface smoothness. Evident second-harmonic generation (SHG) response is observed in single MNWs under excitation from pulses with 1064 nm wavelength and 10 ps duration. The SHG conversion efficiency is approximately 8.4%.
