EXCITON STATES AND LUMINESCENT PROPERTIES IN ONE-DIMENSIONAL SEMICONDUCTOR POLYMER AND THE EFFECT OF LATTICE DISTORTION
一维半导体高聚物中的激子态和发光性质及局部晶格畸变所产生的影响——Lancos严格对角化方法

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.
