Study of Adsorbed Ru(bpy)_3~(2+) on Glassy Carbon Electrode and Its Electrochemiluminescence

通过电化学循环伏安法和电致化学发光方法,研究了Ru(bpy)32+在玻碳电极上的吸附,研究结果表明,2Ru(bpy)3+的浓度和与玻碳材料接触的时间,直接影响了Ru(bpy)32+在玻碳上的吸附.还考察了吸附的Ru(bpy)32+在玻碳电极上被氧化后脱附的情况.The adsorption of Ru(bpy) 32+ on a glass carbon electrode has been investigated by cyclic volt-ammetry (CV) and electrochemiluminescence (ECL). Experimental results show that the adsorption of 2Ru(bpy) 3+ on the surface of glass carbon electrode was obviously affected by the concentration of 2Ru(bpy) 3+ and immersion time. The luminescent intensity decreases in the repetitive CV scan caused by the divorce of the oxidation product, Ru(bpy) 33+ , which made a great intensity change in the initiatory of ECL measurement.国家自然科学基金(No20375033);; 福建省科技项目(2005I-030)资助项

基于变换光学的旋转黑洞模拟

在变换光学和天文学的学科交叉中,黑洞模拟一直是一个重要的课题.随着黑洞照片的公布,相关研究已成为热点.在此之前,科研工作者们模拟的史瓦西黑洞并不像真实黑洞那样,光线在进入黑洞时的状态并不是旋转的.为了更好地模拟真实黑洞的特性,将保角变换得到的折射率分布结合已有的旋转器件合成一个新型的旋转器件,即旋转黑洞,并在其中内置一个吸收体来模拟旋转黑洞附近的光学行为.通过高斯光波的传输以及光线追踪仿真,从波动光学和几何光学两个角度验证了光线旋转进入模拟器件后将被吸收而无法逃逸的特性.国家自然科学基金（11874311
