EXCITON ABSORPTION IN THE PRESENCE OF EXCITED F CENTERS (II)

A rich spectrum of absorption bands is observed at 7 K near the fundamental absorption edge of KI, RbI, CsI and RbBr crystals containing F-centers in the relaxed excited state. The large population of excited F-centers necessary for these experiments is achieved with a Q-switched Ruby laser. The res...

description A rich spectrum of absorption bands is observed at 7 K near the fundamental absorption edge of KI, RbI, CsI and RbBr crystals containing F-centers in the relaxed excited state. The large population of excited F-centers necessary for these experiments is achieved with a Q-switched Ruby laser. The results are discussed in terms of models of excitons formed near excited F-centers. (Author)
