Optical absorption and optically stimulated luminescence measurements have been made on RbCdF3:Mn2+. We show that there is an ultraviolet (UV) response that covers the UV spectrum and hence this compound is applicable for passive UV detection and dosimetry. There is a fast UV-A and UV-B stimulated luminescence decay when compared with the bleaching of the deep UV induced optical absorption that can be explained in terms of a distribution of carrier traps with different detrapping rates.
