Electrons that are excited to a higher energy level may be transferred to an electron acceptor or may return to a ground state. If the latter occurs, energy will be released in a process known as:

• photoelectron degradation

• fluorescence

• photoelectron hydrolysis

• porphryin

• photoelectron deconfiguration
