摘要：
We use Lanczos exact diagonalization method to analyze the energy and the wave functions of exciton states in one-dimensional semiconductor polymer with electron-electron interactions. On the basis of this we further calculate the effect of the local lattice distortion on the exciton states and luminescent properties and find that the efficiency of luminescence is proportional to the strength of local lattice distortion under special electron-electron interaction parameters.
