In this work, we investigated the aluminum content effect on optical, electrical and dielectric properties of mixed metal oxides (MMOs), derived from calcination at 726 K of solid solution series of nitrate intercalated Mg_1-xAl_x Layered Doubles Hydroxides (x = 0.167, 0.20, 0.25, 0.33). Subsequently, the MMOs were characterized by X-Ray Diffraction, and analyzed by Inductively Coupled Plasma, Scanning Electronic Spectroscopy, Diffuse Reflectance spectroscopy and Impedance Spectroscopy. It's was noticed that an increase of aluminum content favorites a blue shifting of the light, increase of the dielectric constant and conductivity at high frequencies. Higher aluminum content exhibited a stronger absorption of UV light with average band gap of 6.29 eV and intense light reflectance in Vis-NIR light, whereas lower aluminum content showed lower values of dc ionic conductivity, dielectric constant and dielectric loss tangent. Moreover, the electrical, dielectric and optical parameters of MMOs were reported and discussed.

在这项工作中，我们研究了铝含量对混合金属氧化物 (MMO) 的光学、电学和介电性能的影响，这些金属氧化物源自在 726 K 下煅烧固溶体系列的硝酸盐插层 Mg _1-x Al _x层状双氢氧化物 ( x = 0.167、0.20、0.25、0.33）。随后，MMO 通过 X 射线衍射进行表征，并通过电感耦合等离子体、扫描电子光谱、漫反射光谱和阻抗光谱进行分析。注意到铝含量的增加有利于光的蓝移、高频下介电常数和电导率的增加。较高的铝含量表现出更强的紫外线吸收，平均带隙为 6.29 eV，在可见光-近红外光中具有强光反射率，而较低的铝含量表现出较低的直流离子电导率、介电常数和介电损耗角正切值。此外，报告和讨论了 MMO 的电、介电和光学参数。
