Abstract
Under Bose and non-Bose approximations, the squeezing, antibunching and sub-Poisso-nian statistics of one-exciton and two-exciton in the Dicke and Fock superposition states are discussed. The recombination radiation of excitons in these superposition states can also have these non-classical effects. The results obtained in various situations are compared and explained.
