Sm, Eu and Yb act as electron trapping and recombination centres, while Ce, Pr and Tb act as hole trapping centres. In this work we present evidence that recombination is by means of hole release from Pr and Tb instead of the more common electron release. The hole trap depth appears 1.33 eV for Pr and 1.28 eV for Tb. The trapped holes are released from Pr or Tb and recombine with the trapped electrons on Sm, Eu or Yb to give characteristic trivalent emission from Sm, Eu or Yb with main emissions at ~600 nm, ~617 nm or ~980 nm, respectively. Lanthanum was introduced in Gd1-xLaxAlO3:Eu ,Pr and Gd1-xLaxAlO3:Eu ,Tb (x=0, 0.25, 0.5 and 1) to engineer the valence band energy and there with to change the hole trap depth. The vacuum referred binding energy (VRBE) diagram of Gd1-xLaxAlO3 (x=0, 0.25, 0.5 and 1) in Figure 1 has been constructed by combining low-temperature VUV spectroscopy and thermoluminescence results. The diagram shows that the valence band moves upwards and the trap depth related to Pr or Tb can be reduced to 0.65 eV or 0.56 eV with increasing the content of La from 0% to 100%. Spectroscopic data needed for construction of the VRBE diagram and TL spectra confirming the reducing of the hole trapping depth will presented. Figure 1.
