Currently in literature, "charged exciton"and "trion"are often confused with each other and mostly considered the same. In this work we show that these terms might actually describe different quasi-particles. Energies and binding energies of both charged excitons and trions in 2D parabolic quantum dots have been calculated as functions of confinements of charge carriers in a quantum dot, using the unrestricted Hartree-Fock method. It is shown that the binding energies of the charged exciton and the trion behave differently in regard to the ratios of the confinements of the electron and the hole. The effect of the external magnetic field on the binding energies of charged excitons has also been considered.
