The development of integrated multifunctional materials with transparent characteristics meets the requirements of optoelectronics and communication. The coupling of stimuli-responsive materials has become a frequently considered strategy. Experimentalists not only search for photonic materials with excellent physical and chemical properties, but also pursue precise and reversible spectral modification. In this study, the luminescent center Ni2+ is artificially introduced into the transparent LiNbO3 nanoferroelectric photonic materials. The Ni2+ ion-based transparent photonic materials exhibit novel complete ultra-broadband emission in the whole near-infrared region. Until now, the ultra-broadband emission was realized by codoping of several active doping ions. In addition, the emission intensity and wavelength of the luminescent center are modified accurately and reversibly by field-induced nanoscale structural transformation. The Ni2+ ion-based transparent nanoferroelectric photonic materials provide an easy way to develop tunable lasers and ultra-broadband optical amplifiers.
具有透明特性的集成多功能材料的发展满足了光电子学和通信的需求。刺激响应材料的耦合已成为一种经常被考虑的策略。实验人员不仅寻找具有优异物理和化学性质的光子材料，还追求精确且可逆的光谱改性。在本研究中，发光中心Ni2+被人工引入到透明的铌酸锂纳米铁电光子材料中。基于Ni2+离子的透明光子材料在整个近红外区域展现出新颖的完整超宽带发射。到目前为止，超宽带发射是通过几种活性掺杂离子的共掺杂实现的。此外，通过场诱导的纳米级结构转变，发光中心的发射强度和波长被精确且可逆地改性。基于Ni2+离子的透明纳米铁电光子材料为开发可调谐激光器和超宽带光放大器提供了一种简便方法。
