摘要：

A neodymium-based self-activated and self-frequency-doubling crystal Nd2CaB10O19 has been grown through the high temperature solution method using CaO-Li2O-B2O3 flux for the first time. It crystallizes in noncentrosymmetric monoclinic space group C2 (No. 5) with unit cell parameters of a = 10.9278(17) angstrom, b = 6.5176(9) angstrom, c = 9.0254(15) angstrom, beta = 91.758(7)degrees, and Z = 2. The crystal structure contains B5O12 double-ring pentaborate groups, which are linked together to form an infinite two-dimensional double layer. Nd2CaB10O19 has a high Nd3+ concentration (6.22 x 10(21) ions/cm(3)) and exhibits a moderate second harmonic generation response (0.6 x KDP), an intense fluorescence-emission in the near infrared range, and a moderate fluorescence lifetime. Moreover, the optical properties of Nd2CaB10O19 were theoretically analyzed by first principles calculations.
