本文配制了系列掺锌铌酸锂多晶料，测量了掺锌铌酸锂的熔化温度及居里温度随掺锌量的变化。用熔融提拉法生长了不同掺锌量的铌酸锂单晶。研究了锌在晶体中的分凝、晶体的抗光折变能力和倍频转换效率。实验结果表明：（１）在铌酸锂晶体中，随掺锌量的增加，ＬｉＮｂＯ３：Ｚｎ的熔化温度呈下降趋势，而居里温度线性上升。（２）在掺锌铌酸锂晶体中，调节锌的掺杂量，可以找到分凝系数近于１的掺锌浓度。（３）当掺锌量大于７ｍｏ１％时，ＬｉＮｂＯ３：Ｚｎ晶体与ＬｉＮｂＯ３：Ｍｇ具有同样的抗光折变能力，前者的倍频转换效率比后者稍大。
In this paper, a series of zinc-doped lithium niobate polycrystalline materials were prepared, and the melting temperature and the Curie temperature of zinc-doped lithium niobate were measured. The lithium niobate single crystals with different zinc content were grown by the melt pulling method. The segregation of zinc in the crystal, the photorefractive ability of the crystal and the frequency doubling conversion efficiency were studied. The experimental results show that: (1) In the lithium niobate crystals, the melting temperature of LiNbO3: Zn decreases with the increase of zinc content, while the Curie temperature increases linearly. (2) In the zinc-doped lithium niobate crystals, the doping amount of zinc can be adjusted to find the doping concentration of zinc near the segregation coefficient of 1. (3) When the zinc content is more than 7mol%, the LiNbO3: Zn crystal has the same photorefractive ability as LiNbO3: Mg, and the former has a slightly higher frequency doubling conversion efficiency than the latter.
