Abstract Super broadband NIR (near-infrared) emission and energy transfer of Nd–Bi–Er co-doped transparent silicate glass-ceramics under excitation 808 nm laser diode were investigated. Super broadband NIR emission in Nd–Bi–Er co-doped extending from 1000 to 1600 nm with a full-width at half-maximum (FWHM) of 600 nm were observed. This result is due to the overlapping NIR emission band centered at 1275 nm (ES1 → GS) of Bi-related and NIR emission band centered at 1063 nm (4F3/2 → 4I11/2) of Nd3+ as well as NIR emission spectral band centered at 1546 nm (4I13/2 → 4I15/2) of Er3+. At the same time, the energy transfer processes between Bi-related, Nd3+ and Er3+ were also discussed and proposed.

Nd-Bi-Er共掺杂透明硅酸盐玻璃陶瓷中的超宽带近红外发射和能量转移

摘要 研究了 Nd-Bi-Er 共掺杂透明硅酸盐玻璃陶瓷在 808 nm 激光二极管激发下的超宽带 NIR（近红外）发射和能量转移。观察到 Nd-Bi-Er 共掺杂中的超宽带 NIR 发射从 1000 到 1600 nm，半峰全宽（FWHM）为 600 nm。该结果是由于以 1275 nm (ES1 → GS) 为中心的 Bi 相关的 NIR 发射带和以 1063 nm (4F3/2 → 4I11/2) 为中心的 Nd3+ 的 NIR 发射带以及 NIR 发射光谱带的重叠在 1546 nm (4I13/2 → 4I15/2) 的 Er3+。同时，还讨论并提出了Bi相关、Nd3+和Er3+之间的能量转移过程。
