Luminescence and excitation spectra for YF3:Gd3+, YF3:Pr3+, and YF3:Pr3+,Gd3+ have been studied in the vacuum ultraviolet (VUV) spectral region at room temperature. In YF3:Gd3+, Gd3+ ions absorb VUV light ranging from 150 to 200 nm due to $4 f$–$4 f$ transitions, yielding an ultraviolet (UV) luminescence line at 311 nm originating from the $4 f$–$4 f$ transition ($\text{$^{6}$P$_{7/2}$}\rightarrow\text{$^{8}$S$_{7/2}$}$ state). In YF3:Pr3+,Gd3+, Pr3+ ions absorb the VUV light (150–200 nm) due to $4 f$–$5d$ transitions, and the absorption gives rise to the UV luminescence of Gd3+ ions that is much stronger than that of YF3:Gd3+. In this paper, we discuss the energy transfer process from Pr3+ to Gd3+ ions in YF3:Pr3+,Gd3+ excited by VUV light.
