摘要：

For the explorations of deep ultraviolet (DUV) nonlinear optical (NLO) borates, a type of important optoelectronic material, the (BO3)(3-) group has been long regarded as the sole microscopic optically-active unit, and toxic Be-containing raw materials are frequently-adopted. Herein, a new DUV NLO crystal, Cs2Al2(B3O6)(2)O (CABO), was designed and synthesized by simultaneously replacing the (BO3)(3-) groups and Be2+ cations for (B3O6)(3-) units and Al3+ cations in Sr2Be2(BO3)(2)O, which possesses a favorable structure, through a chemical co-substitution approach. CABO exhibits a considerable DUV NLO capability because of the wide band gap and large birefringence originating from the [Al-2(B3O6)(2)O](2-) double layers. Remarkably, CABO melts congruently and does not contain the toxic beryllium, which is favorable for bulk-size crystal growth and practical applications.
