Thus, atomic emission spectroscopy is a process in which the light emitted by excited atoms or ions is measured. The emission occurs when sufficient energy (which may be thermal, light or electrical) is provided to excite a free atom or ion to a higher unstable energy state (the atomic absorption process). At low temperatures, few atoms are excited.
