abstract = {The d-f emission from Ce3+ and Pr3+ in garnets is
attracting considerable attention, especially in relation to
application in white light LEDs and scintillators. An
important aspect is the luminescence quenching temperature
TQ. It is not trivial to determine TQ and to unravel the
quenching mechanism. In this paper the TQ of d-f emission
for Ce3+ and Pr3+ are determined by temperature dependent
lifetime measurements. The results show a TQ for Pr3+ of 340
K for Y3Al5O12:Pr3+ (YAG:Pr) and 680 K for Lu3Al5O12:Pr3+
(LuAG:Pr). For Ce3+ the TQ is too high to measure. An onset
of quenching above 600 K (YAG:Ce) or 700 K (LuAG:Ce) is
observed. The differences in TQ between YAG and LuAG are
explained by a smaller Stokes shift for the d-f emission in
LuAG (∼2300 cm−1) compared to YAG (∼2750 cm−1)
derived from low temperature luminescence spectra. The large
difference in TQ between Ce3+ and Pr3+ is related to the
smaller energy difference between the lowest energetic fd
state of Pr3+ and the next lower 4f2 state (3P2) compared to
the 5d – 4f1(2F7/2) energy difference for Ce3+. Both
observations are consistent with luminescence temperature
quenching by non-radiative relaxation from the 5d state to
the 4f state described by a configurational coordinate
diagram and not by thermally induced photoionization.},
