PL time profiles and fitting results. (a) PL time profiles of the Si-ND array at different energy regions. Solid lines are the result of global fitting analysis. (b, c, d) Typical fitting results of the PL time profile using a triple exponential function, where the PL time profile is deconvoluted with an instrumental response function. A black line shows a fitting calculation, and each decaying component is shown by a narrow line. The upper panel shows a residual difference between the experimental and simulated values.
