Luminescence and Photoconductivity of Solids

Abstract

WHEN ultra-violet radiation is absorbed by atoms in a solid, one of two things may happen. Electrons may be freed from the parent atoms or impurity centres, in which case these electrons are able to take part in conduction processes and are said to be in the conduction band. On the simplest view, it follows from this that photoconduction is to be associated with a hyperbolic decay law. On the other hand, electrons may be raised to states lying below the conduction band, in which case the electrons are still bound to the parent atoms and are unable to take part in conduction. Electrons in this condition are said to be in excitation states, and the phosphorescence decay law should then be exponential.
