  • Photon yield for ultraviolet and visible emission from CF4

    2010-5-1Carbon tetrafluoride (CF 4) photon yield, defined as the number of photons emitted per 1 MeV of energy deposited in the gas is reported for the ultraviolet (220–500 nm) and visible (500–800 nm) emission in the pressure range from 0.5 to 5 bar.An Am-241 α-source was used for gas excitation. Emission spectra (corrected for the response of the detection
