“…The energies of appropriate PI (charge transfer) transitions calculated basing on the concepts of Jorgensen's RESPET model [1,4] coincide very well with the experimental values [5][6][7]. In this model, after correction for multiplet splitting (ΔΕΜC) of the initial and final states, the ionization energy depends linearly on " q'', i.e.…”

“…From the photoEPR experiments we know the positions of Eu 2 +/3 + and Yb2+/3+ energy levels in ZnS [5,7]. In our previous work [3] we have shown that the maximum around 26000 cm-1 in the excitation spectum of the Tm3 + 1G4 3H6 emission in ZnS, observed by Zimmermann and Boyn [6], should be attributed to Τm3 + + hv ÞTm2 + + hvb PI transition.…”

“…In order to consider possible quenching models, it is necessary to first discuss the excitation mechanism. The most widely accepted model for energy transfer between the semiconductor host and the rare-earth ion was first discussed for II-VI compounds 19,20 and InP:Yb, 21,22 followed by a similar model for GaAs:Er. 18,23 In this model, the rare-earth ion introduces either an electron trap below the conduction band or a hole trap above the valence band.…”

“…Such direct radiative recombination of the rare earth bound exciton was observed in few cases only [9][10][11]. The PL(T) measurements showed in fact a new PL band at increased temperature, whose appearance might be correlated with the decay of the 4f-4f PL of Yb 3 + [12].…”
