The luminescence shows the characteristic doublet of {\em R} lines at 14 400 cm$^{-1}$ of the spin-forbidden ligand field transition $^{$^{2}E}$({\em t}2{\em g}3)→$^{$^{4}A$_2$}$({\em t}2{\em g}3) of the [Cr(ox)$_3$]$^{3-}$ chromophore. The resonant energy migration within the {\em R}$_1$ line shows that the three-dimensional crystallographic structure is preserved during the coating process. The observation of the {\em R} lines of [Cr(bpy)$_3$]$^{3+}$ at 13 710 cm$^{-1}$ indicates that a small fraction of Cr$^{3+}$ ions migrate from the oxalate network to the tris-bipyridine cation site in the cavities of the network.}}, year = {2005} }
