Abstract

Results of a first investigations on luminescence in Nd[Formula: see text] doped Sr3Bi(PO4)3 are presented. Typical emission is in near infrared (NIR) region consisting of lines attributable to f–f transitions. The excitation also comes from f–f transitions involving higher energy levels, spanning a broad spectral range starting from near ultraviolet (nUV) running through NIR. As much as 5[Formula: see text]mol.% of Nd[Formula: see text] could be doped before concentration quenching of luminescence set in. The quenching was attributed to energy transfer between Nd[Formula: see text] ions taking place through a multipolar mechanism; the critical distance being 21.64[Formula: see text]Å. An easy synthesis method involving low-cost chemicals and favorable luminescence properties makes this phosphor a potential candidate for NIR applications.

掺杂稀土离子 (Nd3+) 的 Sr3Bi(PO4)3 荧光粉的合成与发光研究

本文介绍了对掺杂钕[式：见正文]的 Sr3Bi(PO4)3 的发光进行首次研究的结果。典型的发射位于近红外（NIR）区域，由 f-f 转变线组成。激发也来自涉及更高能量级的 f-f 转变，跨越了从近紫外（nUV）到近红外的宽光谱范围。掺杂多达 5[式：见正文]mol.%的钕[式：见正文]后，才会出现浓度淬灭发光现象。淬灭归因于钕[式：见正文]离子之间通过多极机制进行的能量转移；临界距离为 21.64[式：见正文]埃。这种荧光粉的合成方法简便，涉及的化学品成本低，而且具有良好的发光特性，因此有可能应用于近红外领域。
