Fluorescence intensity as a function of the slit width. Three pump laser intensities were tested and appear in legends. Numerical data (black dots) is fit with exponential and saturation models – Eqs. 1(a) and (b), respectively. Material, molar concentrations and other information appears in legends and titles.
