Probing the R lines in tris(acetylacetonato) chromium(III) and tris(3-bromo-acetylacetonato) chromium(III) by luminescence and excitation line narrowing spectroscopy.


Site-selective and narrowed luminescence and excitation spectra in the region of the (2)E <-- (4)A 2 transitions are reported for single crystals of Al(acac) 3/Cr(III) and Al(3-Br-acac) 3/Cr(III) (where acac is acetylacetonate). The R 2 line is pronounced in the brominated system and displays a comparable oscillator strength as the R 1 line. The (2)E… (More)
