摘要

通过固态合成和 DSC 方法研究了 Na3Nd（BO3）2-NdBO3 相图。Na3Nd(BO3)2、Na3Nd2(BO3)3 和 NdBO3 是由 Na2O-B2O3-NaF 通量自发结晶生长出来的。在 875 纳米和 1054 纳米波长处记录了典型的 4F3/2 → 4I9/2 和 4F3/2 → 4I11/2 电子跃迁的 Nd3+ 发光。Na3Nd2(BO3)3 晶体的发光积分强度最大，是 NdBO3、Na3Nd(BO3)2 的两倍多。

Phase Relations Between Na3Nd(BO3)2, Na3Nd2(BO3)3, NdBO3 and Their Luminescence Properties

The Na₃Nd(BO₃)₂-NdBO₃ phase diagram was investigated by the solid-state synthesis and DSC methods. Na₃Nd(BO₃)₂, Na₃Nd₂(BO₃)₃ and NdBO₃ were grown by spontaneous crystallization from the Na₂O-B₂O₃-NaF flux. Typical Nd³⁺ luminescence of ⁴F_3/2 → ⁴I_9/2 and ⁴F_3/2 → ⁴I_11/2 electron transitions at 875 nm and 1054 nm were registered. Maximum integral intensity of the luminescence was observed for Na₃Nd₂(BO₃)₃ crystals, more than twice that of NdBO₃, Na₃Nd(BO₃)₂.
