✦ Synopsis

Saturation of the fluorescenc=z of tetracene in anthracene crystal with increasing excitation was ob--served at liquid nitrogen temperature. Samples were excited by a iow energy electron beam (X 20 kev). The reIation between t!e fluorescence intensity and the electron beam density was explained by solving a steads state rate equation. It was concluded that the snturation of the fluorescence is due to the depletion of ihe tetracene molecules of the ground state .
