Abstract

Nanocomposites and nano ceramics are very important materials due to its wide applications in the field of energy supply and storage, communications, refractory and electrical devices etc. The optical properties, nature of dielectric relaxation mechanism, loss factor etc are very important in deciding their use. Magnesium oxide is basically an insulator material and when combined with a transparent semiconductor like ZnO, its properties change drastically .The method of preparation can also often be a determining factor in shaping a nanoceramics. In the present study mainly composition and its effects in optical and dielectrical properties are probed through Cole-Cole Plots.

摘要

纳米复合材料和纳米陶瓷由于在能源供应和存储，通信，耐火材料和电气设备等领域的广泛应用而成为非常重要的材料。光学特性，介电弛豫机理的性质，损耗因子等对于决定其用途非常重要。 。氧化镁基本上是一种绝缘体材料，当与诸如ZnO的透明半导体结合使用时，其性能会急剧变化。制备方法通常也可以成为决定纳米陶瓷成形的决定性因素。在本研究中，主要通过Cole-Cole曲线探讨了组成及其对光学和介电性能的影响。
