摘要
测量了新制丙氨酸咪唑钐水溶液的三维荧光激发和发射光谱 ,分析了在不同波长激发光作用下的荧光特征 ,与配体咪唑、α 丙氨酸及氯化钐的荧光谱进行了比较 ,讨论了模型化合物上转换荧光中的双光子和多光子加合现象并发现在 1 0 - 2 - 1 0 - 4
The three dimension fluorescence excitation and emission spectrum of the aqueous solution of alanine imidazole Sm has been first measured,the compound′s fluorescence property with different wavelength excitation light was analysised,writer also compared its fluorescence spectrum with imidazole,α alanine and SmCl 3′s ,the additive phenomenon of double light and multi light in the up conversion fluorescence of heading compound was discussed. The range of its concentration between 10 -2 ～10 -4 mol/L,writer found that the fluorescence intensity of the compound is proportional to its concentration.
