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 (LiNbO 3 ) crystals from niobium carbide MXene (Nb 2 CT x ). The formation of high‐aspect‐ratio LiNbO 3 rhombic crystals is confirmed by extensive structural analysis. The ferroelectricity of MXene‐derived LiNbO 3 is verified, using standard ferroelectric and dielectric measurements. In addition, for the first time, Pr 3+ ‐doped LiNbO 3 crystals are synthesized with simultaneous visible photoluminescence (PL) from Nb 2 CT x MXene. 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.
