Abstract
The decay of the intensity of the luminescence in a-As2S3 with the energies of 1.16 and 1.57 eV was measured from 10-8 sec to 2×10-3 sec at 4.2 K. The shape of the decay curves shows three kinds of luminescence whose intensity decays according to the empirical decay function (f(t)=t n-1exp -(t/τ) n ) with effective decay times (τ) of 2×10-8, 2×10-6 and 2×10-4 sec. Each luminescence process is discussed in this paper.Keywords
