Creation of lattice defects by electronic excitation in alkali halides

A theoretical study of desorption induced by electronic transitions in alkali halides

“…Accordingly, only an excited self-trapped exciton can lead to desorption of halogen atoms. It has been established that defect formation in the bulk of alkali halides is induced from excited states of the self-trapped exciton, not from the lowest state of the self-trapped exciton [40]. The conversion from an excited state of the self-trapped exciton to a pair consisting of an F centre and an H centre is considered to occur following an anti-bonding adiabatic potential surface which connects these two states, in agreement with ref.…”

Creation of storage centers in CsBr:Eu2+ needle image plates by vacuum ultraviolet radiation

“…We suggest that the storage centers originate predominantly from to the well-known "Itoh-process" 14,15,22 which is valid for alkali halides. It is very probable that the creation of the F-and V K -centers in Eu-doped CsBr occurs similarly to the undoped CsBr.…”

Defect formation in solids by decay of electronic excitations

“…Is. Расчеты показали 1S1 , что такой переход может осуществ-ляться за 10" 11 с, что согласуется с экспериментом 102 > 134 . Рассмотренная модель распада е° с рождением F, Н-пар предсказывает возможность создания дефектов при оптическом возбуждении e°s, имевших до этого электронную компоненту в состоянии Is.…”
