Einstein shift短语¹⁴⁴⁹⁷²⁺²
基本例句
n.物红移;引力红移;天谱线引力位移
With the concentration increasing,the fluorescence spectrum changed from single peak to double peak then to single peak again,and the double peak wholly appear Einstein shift.随着溶液浓度的增大,荧光光谱出现了由单峰到双峰再到单峰的变化,且第一、第二荧光峰分别出现红移。
In the UV-vis of the subtitutional phthalocyaninatometal axis complex, the Q band of phthalocyaninatometal axis complex iseinstein shiftmore than 4 nm comparing with the phthalocyaninatometal.由于苯氧基的引入,共轭体系增加,使酞菁Q带表现出一定程度的红移,而B带明显变宽。 而在轴向配合物的紫外-可见光谱图中我们可以看到,生成配合物的Q吸收带比未生成配合物酞菁的Q吸收带红移了4个多纳米,且吸收峰明显变窄。
Ag was deposited by H 2 reduction on the surface of TiO 2 nanoparticles. The results of SEM, XRD and UV-vis show that Ag distributes uniformly on the TiO_2 surface and the Einstein shift can be observed clearly in the UV-vis adsorption spectrum.用H2气还原法制备了表面沉积Ag的纳米TiO2,通过对样品SEM、XRD、UV Vis漫反射光谱分析,结 果表明,金属Ag在TiO2表面呈细小而均匀的分布,UV Vis光谱上的吸收阈值显著红移。
It can be seen from the UV-vis of the subtitutional phthalocyaninatometal that the Q band of phthalocyaninatometal iseinstein shiftwith the subtitutional group and B band of phthalocyaninatometal broadens greatly .结果显示,各个金属取代酞菁分别有与它们分子量相吻合的分子离子峰。 在各个酞菁的紫外-可见:光谱图中能看到明显的两个酞菁特征吸收带:Q带和B带。
