Abstract
AbstractUsing a narrow band dye laser three excited states of the I2 bound exciton in CdS can be detected in the excitation spectrum of luminescence. Their behaviour at different excitation intensities is investigated giving essential conclusions to distinguish EM‐ and I2‐emission. From the corresponding lines in the transmission spectrum the oscillator strengths are estimated. The properties of the excited states refer to a deuteron‐like model of exciton weakly bound to the donor.
