Abstract: | - By zone melting purification and doping with divalent ions, specimens of CsI (pure), CsI/Ca2+, CsI/Sr2+, and CsI/Mn2+ crystals were prepd. The blue 4300-A. component was enhanced by the doping but independent of the chem. nature of the impurity. The uv (exciton) component remained unaffected. Thermoluminescence and uv irradn. show that the complex formed by the assocn. of an ion and a cation vacancy is probably responsible for both the electron traps and the luminescent centers which are characteristic of the blue emission. The thermal release of selftrapped holes and their recombination with trapped electrons and the ir release of electrons and their recombination with Vk-centers are studied and discussed. |
