In this paper we will present VUV spectroscopy experiments performed at the Superlumi station of Hasylab, DESY, Hamburg, on samples of BaF 2 crystals activated with Ce and BaF 2 , (Ba,La)F 2 crystals activated with Er. The results of these experiments include time resolved luminescence and luminescence excitation spectra obtained under wavelength selective VUV and UV excitation...
Luminescence and luminescence excitation spectra of BaF 2 :Er in UV and VUV have been measured at Superlumi station in Hamburg, in search for fast and efficient VUV scintillator materials. Although, under selective VUV excitations, we observe the 4f 10 5d–4f 11 VUV emission, it is relatively slow and is not efficiently excited at VUV wavelengths below 124nm. The structure observed...
