| 中文摘要 | the electronic structure and exciton states of cylindrical zno nanorods with radius from 2 to 6 nm are investigated based on the framework of the effective-mass theory. using the adiabatic approximation, the exciton binding energies taking account of the dielectric mismatch are solved exactly when the total angular momentum of the exciton states l = 0 and l = +/- 1. we find that the exciton binding energies can be enhanced greatly by the dielectric mismatch and the calculated results are almost consistent with the experimental data. meanwhile, we obtain the optical transition rule when the small spin-obit splitting delta(so) of zno is neglected. furthermore, the radiative lifetime and linear optical susceptibilities chi(w) of the exciton states are calculated theoretically. the theoretical results are consistent with the experimental data very well.
