Abstract
Luminescence spectra and decay kinetics of the fast intrinsic luminesc ence of RbI and KI crystals at temperatures of 80 and 300 K have been measured with pulsed X-ray synchrotron radiation (SR) excitation. At 8 0 K the emission spectra show the well-known fast emission bands cente red at 3.84 eV in RbI and at 4.15 eV in KI. At room temperature subnan osecond (similar to 100 ps) emission bands with non-exponential decay kinetics are observed at 3.7 eV in RbI and at 4.0 eV in KI. These two bands may be associated with high temperature fast intrinsic luminesce nce of CsI.
