【摘要】在 Fe∶Li Nb O3 中掺进 3 mol%和 6mol% Mg O,生长了 Mg∶Fe∶L i Nb O3 晶体 .测试了 Mg∶Fe∶Li Nb O3 晶体抗光致散射能力、衍射效率、响应时间和光电导 .推导响应时间与光电导之间的关系 .在 Fe∶Li Nb O3 晶体中掺进 6mol%的 Mg2 + ,它的抗光致散射能力比Fe∶L i Nb O3 晶体提高一个数量级 ,响应速度比 Fe∶Li Nb O3 晶体提高四倍更多还原

【Abstract】 Doping 3mol% and 6mol% MgO in Fe∶LiNbO 3,Mg:Fe∶LiNbO 3 crystals were grown.The photo scattering resistance ability,diffraction efficiency,response time and photoconduction of Mg:Fe∶LiNbO 3 were measured.The response time dependence on the photo conduction was deduced.The photo scattering resistance ability of Mg(6mol%):Fe∶LiNbO 3 is one order of magnitude higher than that of Fe∶LiNbO 3 and the response rate of Mg(6mol%):Fe∶LiNbO 3 is four times faster than that of Fe∶LiNbO 3.更多还原
