“…The crystal obtained by homogeneous doping with a zinc concentration of 4.68 mol% had the least number of defects, including those in the empty octahedron, which indicates a higher degree of structural homogeneity of this crystal compared to the others. This result was consistent with the PILS and conoscopy data obtained by Masloboeva et al, [ 24 ] where it was shown that crystals grown by homogeneous doping had a high resistance to laser damage, which makes them attractive for use as a medium for frequency conversion.…”

The correlation between photoluminescence in the near‐IR region and point defect centers in the LiNbO3 crystals co‐doped with Zn and Mg both by homogeneous and direct methods has been studied. X‐ray diffraction (XRD) analysis shows that the LiNbO3:Zn:Mg (4.68:0.9 mol%) crystal obtained by homogeneous doping has the least number of intrinsic defects compared to the others. It has been established that ZnLi defects stimulate photoluminescence (PL) in the near‐IR region of the luminescence spectrum in the LiNbO3:Zn:Mg crystals obtained by homogeneous doping. The LiNbO3:Zn:Mg (4.68:0.90 mol%) crystal has the maximum PL intensity and the LiNbO3:Zn:Mg (3.83:0.97 mol%) crystal has the minimum. Both crystals are doped homogeneously. Such defects as niobium vacancies (VNb) and niobium in the empty octahedron (Nboct) are suggested as luminescence quenchers in the co‐doped crystals.

“…Generally, congruent LiNbO 3 melt composition is used in Cz method, leading to the growth of congruent LiNbO 3 (CLN) crystal, which suffers from Li deficient (about 48.6 mol. % Li 2 O) [12,13]. However, The CLN crystal contains a high concentration of intrinsic defects in the form of Nb anti-sites (Nb Li 5+ ) and Li vacancies (V Li − ) that limit its scope for optical applications [14,15].…”

Lithium niobate (LiNbO3) crystals are important dielectric and ferroelectric materials, which are widely used in acoustics, optic, and optoelectrical devices. The physical and chemical properties of LiNbO3 are dependent on microstructures, defects, compositions, and dimensions. In this review, we first discussed the crystal and defect structures of LiNbO3, then the crystallization of LiNbO3 single crystal, and the measuring methods of Li content were introduced to reveal reason of growing congruent LiNbO3 and variable Li/Nb ratios. Afterwards, this review provides a summary about traditional and non-traditional applications of LiNbO3 crystals. The development of rare earth doped LiNbO3 used in illumination, and fluorescence temperature sensing was reviewed. In addition to radio-frequency applications, surface acoustic wave devices applied in high temperature sensor and solid-state physics were discussed. Thanks to its properties of spontaneous ferroelectric polarization, and high chemical stability, LiNbO3 crystals showed enhanced performances in photoelectric detection, electrocatalysis, and battery. Furthermore, domain engineering, memristors, sensors, and harvesters with the use of LiNbO3 crystals were formulated. The review is concluded with an outlook of challenges and potential payoff for finding novel LiNbO3 applications.
