Excimer lamps are being used increasingly as sources of noncoherent UV radiation. An excimer is a diatomic molecule, typically a homonuclear noble gas or noble gas–halogen complex, in an excited electronic state that is more stable than its ground state, such that the molecule breaks apart when the excitation energy is released in the form of a UV photon. Depending on the excimer, the radiation is emitted in one or more narrow wavelength bands in the UV‐C region. Phosphors may be used to shift and broaden the emission spectrum of the lamp for various applications.
