浸渍法制备Al_2O_3:Ni^(2+)及其EPR研究

Study of EPR spectra and synthesis of Al_2O_3:Ni^(2+) by inpregnation method

使用浸渍法制备了Al_2O_3:Ni^(2+)晶体,并对不同温度400℃～1000℃焙烧的7种样品进行了分析,采用日本岛津电子公司生产的JES-FA200电子顺磁共振谱仪测试了样品的电子顺磁共振谱,分析了EPR信号对应的离子归属,对今后使用电子顺磁共振研究Al_2O_3:Ni^(2+)提供了借鉴参考依据.

The Al2O3：Ni2＋ crystals was made with the impregnation method an 400°C-1000°C. We got seven different samples and analyzed the samples by the JES-FA200 EPR spectrometer which was made by JEOL. We make a correspondence analysis of the EPR signals. This work will provide a reference for the future reach of Al2O3：Ni2＋ crystals with EPR spectra.
