摘要
观测了罗丹明101染料在甲醇和酸性甲醇溶液中的稳态吸收、稳态荧光和时间分辨荧光光谱,得到了吸收与荧光光谱的特征信息以及荧光寿命;通过拉曼光谱、红外光谱和密度泛函理论计算,对罗丹明101染料分子的振动模式进行了指认。研究结果全面系统地表征了罗丹明101染料的光谱特征以及分子结构和振动信息,为罗丹明101染料在染料敏化太阳能电池和生物荧光标记等方面的应用研究提供了依据。
The absorption,fluorescence and time-resolved fluorescence spectra of Rhodamine 101 dye in both methanol and acidic methanol solutions were measured.The authors achieved the characteristic information of the absorption and fluorescence spectra,and obtained the S1 lifetimes.The authors assigned vibrational modes of the Rhodanmine 101 dye molecule through spontaneous Raman spectrum,infrared spectrum,and density function theory calculation.This work systemically characterizes the spectral,molecular structural,and vibrational information of Rhodamine 101 dye molecule,and provides necessary information for the application of Rhodamine 101 dye in dye sensitized solar cell and biological fluorescence marker.
