中文摘要: |
采用水浴法制备了掺锰氧化锌,通过改变反应液中锰离子的浓度获得不同锰含量的氧化锌样品。采用SEM,EDS和XRD对样品的形貌、成分和结构进行了分析,利用矢量网络分析仪AV3618测试了试样在2~ 16 GHz范围的电磁参数。结果显示掺锰氧化锌是单相结构,外形呈棒状,直径为0.3~ 0.5μm,长度为5~ 6μm。掺锰氧化锌的介电谱在5~ 8 GHz存在一个介电损耗峰,该损耗峰随着锰掺杂量的提高,有分裂成双峰的趋势。随着掺锰量的提高,反射率低于- 10 dB的频宽有逐渐向高频移动并逐渐变宽的趋势。 |
英文摘要: |
Mn-doped zinc oxides were prepared through water bath method. By changing the concentration of manganese ions in the reaction solution, zinc oxides with different amount of manganese were obtained. The morphologies, chemical composition and the structures of the samples were investigated by SEM, EDX and XRD respectively. AV3618 vector network analyzer was employed to analyze the electromagnetic parameters of the doped samples in the frequency range of 2~ 16 GHz. The resultsindicate that Mn-dopedZnO is of single-phase structure and a rod-like outline with 0.3~ 0.5μm in diameter and 5~ 6μm in length. There is a dielectric loss peak located at 5~ 8 GHz in the dielectric spectrum and it has a trend of splitting into two peaks as Mn dopant increase. The frequency bandwidth which less than - 10 dB shifts to high frequency and becomes broad with the increase of Mn concentration. |
