【Abstract】 The whole paper separates into two parts. Continuing the first part, the theoretical analysis and the experimental measuring technique of picosecond relaxation time of the organic dyes have been emphatically discussed in this part. Based on the properties of the dyes, a simple theoretical model has been proposed and a funda mental formula has been derived. From this formula, the life-time of excited state S₁ of the dye molecules is experimentally determined by picosecond technique.更多还原
