M. Grinberg et al., INHOMOGENEOUS BROADENING OF (2)E-](4)A(2) FLUORESCENCE IN (CA,ZR)-SUBSTITUTED CD3GA5O12CR3+, Journal de physique. IV, 4(C4), 1994, pp. 465-468
In this contribution we investigate time evolution of the lineshape of
the R line of the Cr3+ in GGG, additionally doped with Ca-Zr (0.45 mo
l/formula), by time resolved spectroscopy at liquid helium temperature
. In theoretical part of the paper we simulate time evolution of the R
line using adiabatic model of the energetic structure of Cr3+, assumi
ng that distribution of crystal field results from the Poisson distrib
ution of Ca-Zr defects.
