Strong fluorescence is observed on the XeI (B→X) excimer band upon excitation of a mixture containing an iodine compound and Xe with 193 nm photons. This emission is observed when I2, CH2I2, CH3I, or CF3I are used as iodine donors. Radiative lifetime and two‐body collisional quenching rate of XeI(B) by Xe, I2, and CH3I have been measured. The relevance of these results with regards to use of this excimer as a source of UV stimulated emission is discussed.
