| Abstract: | In this paper, we obtained the spectra of sodium flourecein in a distilled water solution and common water solution, and then determined its absorption coefficients and estimated the average life--time of fluorescein molecule. Combining with image processing tevhnique, the effects of concentration, laser power, temperature, pHvalue and color filter on fluorescence intensity were discussed in detail. |
