Preferred Label : delayed luminescence;
IUPAC definition : luminescence decaying more slowly than that expected from the rate of decay of the
emitting state. The following mechanisms of luminescence provide examples: ol li
triplet-triplet or singlet-singlet annihilation to form one molecular entity in its
excited singlet state and another molecular entity in its electronic ground state
(sometime referred to as P type), /li li thermally activated delayed fluorescence
involving reversible intersystem crossing (sometimes referred to as E type), and
/li li combination of oppositely charged ions or of an electron and a cation. For
emission to be referred to in this case as delayed luminescence at least one of the
two reaction partners must be generated in a photochemical process. /li /ol ;
