TbCl3 和 lanthanide (III ) 的相互作用 -diketonate 建筑群与(N-vinylpyrrolidone )(PVP ) poly，聚合物用荧光光谱学被学习。面对 PVP，在 TbCl3 的 ethanolic 答案的 Tb3+ 的排放显著地从 PVP 由于刺激精力转移增加了到 Tb3+ 离子，它是与 Tb3+ 4f75d1 层次的直接刺激相比同样有效的更多。相反， NEt4Tb (hfa ) 的排放 4 并且 NEt4Eu (hfa ) 4 建筑群几乎完全在答案包含被熄灭 PVP。PVP 绑了引起了 Ln-hfa 建筑群的分解并且从 ligand 关上了刺激精力转移到射出的 Ln3+ 离子的 Ln3…
To meet the requirements for different practical applications,we investigate the properties of single LaF3 layer deposited by resistive heating Mo-boat( RH) and ion beam sputtering( IBS) in this paper. First,transmittance and reflectance spectra of LaF3 thin films were measured by an UV-visible spectrophotometer,and t…
The CuO nanoplatelets were synthesized by hydrothermal method. The structure and morphology of the CuO nanoplatelets were characterized by TEM and XRD. A new nonenzymatic glucose sensor was constructed by immobilizing the CuO nanoplatelets on glassy carbon electrode with Nafion. The electrochemical performance of the…

采用固相法合成了KSr4(BO3)3∶x Eu2+(KSB∶x Eu2+)荧光粉,通过X射线粉末衍射(XRD)、扫描电镜(SEM)及光致发光光谱分别研究了样品的晶相、形貌及发光性质。XRD研究结果表明制备的样品为正交晶系的KSr4(BO3)3单相。当Eu2+的掺杂摩尔分数x为1.5%时,在激发光谱250~550 nm范围内观察到了两个宽带激发,可归属为Eu2+的4f7-4f65d1跃迁;在400 nm激发下,发射谱呈现出一个不对称的黄色发射带,峰值位于560 nm处,可归属于Eu2+的4f65d1-4f7跃迁。因在KSr4(BO3)3化合物中存在3个Sr格位,根据其光谱特征可推测发射谱中非对称的发射带来源于多个Eu2+发光中心。
我们报导有缺点的 graphene 的调制门的拉曼光谱。我们证明 D 山峰的紧张能被使用门电压 reversibly 调节。这效果被归因于 graphene 水晶格子的化学 functionalization，由包含在在硅和 graphene 之间的接口套住的水层的电气化学的反应产生了。
