Paper Abstract

This paper reports an experimental study of the photoelectron energy distribution in the two-photon photoeffect in CdS under a relatively low excitation. A comparison with the luminescence spectrum obtained on the same sample reveals the energy levels in the forbidden zone. The photoelectron and luminescence spectra were measured under both separate and simultaneous excitation of CdS by He I lamp (21.2 eV) and nitrogen laser (3.7 eV). The maximum laser beam intensity at the sample did not exceed 50 kW/cm2 at a pulse length of 8 ns. A detailed description of the experimental arrangement and of the photoelectron spectrum measurement technique used is given elsewhere.
