An electron absorbs energy when it goes from a ground state to an excited state.
This absorption of energy is what causes the electron to jump levels. When the electron returns to ground state, the energy has to "Go" somewhere, so it is emitted as some type of energy. When you excite copper atoms, the emission occurs as the electron returns to a lower-energy state. This emission takes the form of visible, green light.
