Abstract: We established an expanded energy level system model of 2-(2′-hydroxyphenyl)benzothiazole (HBT) molecule and proposed corresponding numerical simulation algorithm for the dual-wavelength fluorescence phenomenon of organic molecule HBT in specific polar solutions, and verified the accuracy and effectiveness of the proposed algorithm.  The simulation results are similar to the experimental results, indicating that there is a competitive relationship between the fluorescence of HBT molecules at different wavelengths in specific  polar solutions. 

Key words: time-domain finite-difference,  , 2-(2′-hydroxyphenyl)benzothiazole,  , dual-wavelength emission, excited state intramolecular proton transfer
