MXene最近已被用于生长高度织构化的钛酸钾铁电晶体。在此，通过从碳化铌MXene（Nb2CTx）生长铁电和发光的铌酸锂（LiNbO3）晶体进一步证明了MXene的多功能性。通过广泛的结构分析证实了高纵横比LiNbO3菱形晶体的形成。MXene衍生的LiNbO3的铁电性使用标准铁电和介电测量进行验证。此外，首次从Nb2CTxMXene合成了Pr3+掺杂的LiNbO3晶体，同时具有可见光致发光（PL）。这项工作表明，通过利用MXene的2D特性，可以制造用于先进光电应用的高纵横比和良好取向的光致发光铁电晶体。
MXenes have recently been used to grow highly textured potassium niobate ferroelectric crystals. Herein, the versatility of MXenes is further demonstrated by growing ferroelectric and luminescent lithium niobate (LiNbO3) crystals from niobium carbide MXene (Nb2CTx). The formation of high‐aspect‐ratio LiNbO3rhombic crystals is confirmed by extensive structural analysis. The ferroelectricity of MXene‐derived LiNbO3is verified, using standard ferroelectric and dielectric measurements. In addition, for the first time, Pr3+‐doped LiNbO3crystals are synthesized with simultaneous visible photoluminescence (PL) from Nb2CTxMXene. This work demonstrates that it is possible, by using the 2D character of MXenes, to fabricate high aspect ratio and well‐oriented photoluminescent ferroelectric crystals for advanced optoelectronic applications.
