摘要：

Novel KCaR(BO3)(2) (R = La, Pr and Nd) compounds have been obtained by solid-state synthesis. Specifically, single crystals of KCaNd(BO3)(2) and KCaPr(BO3)(2) were grown by using a top seeded solution growth method from the KBO2, flux. These crystal compounds belong to the orthorhombic system, Pbca space group. KCaLa(BO3)(2) exhibits high transparency in the range of 200-900 nm. Pr and Nd compounds have a strong emission bands that are related to the well-known electron transition of Pr3+ (P-3(0) -> H-3(6) at 630 run, P-3(0) -> F-3(2) at 670 nm) and Nd3+ (F-4(3/2) -> I-4(9/2) at 875 nm, F-4(3/2) -> I-4(11/2) at 1054 nm).
