| Abstract: | Copyright © The Author(s) 2018. Y3Al5O12 (YAG) and Lu3Al5O12 (LuAG) doped with rare earth elements are widely used as scintillators, solid state lasers, and phosphors in white light emitting diodes (LEDs). Additionally, (Gd,La)B3O6:Bi has found application as a UV-B emitting phosphor in fluorsecent lamps a long time ago. This paper reports both the photoluminescence (PL) and cathodoluminescence (CL) of Pr3+ or Gd3+ substituted YAG and LuAG in comparison to the widely applied UV-B phosphor (Gd,La)B3O6:Bi under vacuum ultra violet (VUV) and cathode ray excitation, respectively. The powder diffraction pattern, emission, excitation, and reflection spectra and a comparison of the luminescence efficiency are shown and discussed. It turned out that all investigated phosphors show efficient luminescence in the UV-B spectral range. Moreover, it is found that LuAG:Gd has the highest efficiency upon VUV and upon CL excitation too. |
