Abstract

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 4F3/2 → 4I9/2 and 4F3/2 → 4I11/2 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.

Na3Nd(BO3)2、Na3Nd2(BO3)3 和 NdBO3 之间的相位关系及其发光特性
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。
