Emission Spectra in CdS under High Excitation by Electron Beam

An additional peak in CdS was observed on the long-wavelength side of the Ex-LO band in the spontaneous emission spectra under high excitation by an electron beam from 82 to 300 °K. The shift of the additional peak from the free-exciton line increased linearly with temperature. The laser emission oc...

Description
Summary:An additional peak in CdS was observed on the long-wavelength side of the Ex-LO band in the spontaneous emission spectra under high excitation by an electron beam from 82 to 300 °K. The shift of the additional peak from the free-exciton line increased linearly with temperature. The laser emission occurred near the additional peak. The laser-transition mechanism associated with the additional luminescence is discussed.
