Abstract: | The effect of self absorption on the ratio of excimer to monochromophore emission intensities, I_e/I_m, has beenexplored by experimentally changing the solution layer thickness of the emission light path traversed in the solution in theright-angle geometry. The result shows that data obtained by front-face geometry are better than those obtained by right-angle geometry even after correction to zero solution thickness. The correction formula based on geometric optics given byTsai and Torkelson is not adequate. |
