Abstract
Pulsed cathodoluminescence (PCL) of CeF3 crystals was studied using a KLAVI-type setup. PCL was excited by bombarding samples in air at room temperature using a 2-ns pulsed electron beam at an electron energy of 170 keV, current density of 160 A/cm2, and repetition rate of 2.5 Hz. Luminescence and phosphorescence were observed in the UV and visible spectral regions. The phosphorescence is tentatively associated with the Ce2+ ion formation.
