Rhodamine 6G

The chemical structure of Rhodamine 6G is shown at the right. The absorption and fluorescence emission spectra are shown below. The structure, absorption, and fluorescence data were all obtained from the PhotochemCAD package by Jonathan Lindsey. This excellent program allows rapid comparison of spectra and enables one to do a variety of photochemically relevant calculations. Chemical Structure

Absorption

Absorption Spectrum

This is a graph of the molar extinction coefficient of Rhodamine 6G dissolved in ethanol. It was measured by R. A. Fuh on summer, 95 [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. Rhodamine 6G has a molar extinction coefficient of 116,000 M-1cm-1 at 529.75 nm [R. R. Birge, "Kodak Laser Dyes," 1987].

Fluorescence

Emission Spectrum

This is the fluorescence emission spectrum of Rhodamine 6G dissolved in ethanol. The spectrum was taken by R. A. Fuh on summer, 95 using an excitation wavelength of 480 nm [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. The quantum yield is 0.95 [R. F. Kubin and A. N. Fletcher, "Fluorescence quantum yields of some rhodamine dyes.," J. Luminescence, 27, 455-462, 1982].
