The photoluminescence (PL) excitation spectrum (intensity of PL as a function of the wavelength of the exciting light) has been measured over the range 1.0 -1.25 eV for PL at 0.79 eV using a free electron laser (FEL) as the excitation source. At all wavelengths, the PL intensity varies with incident
