Non-photochemical spectral hole-burning in the 2E←4A2 transition of crystalline NaMgAl(oxalate)3·9H2O∶Cr(III)

Abstract

Non-photochemical spectral hole-burning in the 2 E← 4 A 2 transition of crystalline NaMgAl(oxalate) 3 ·9H 2 O∶Cr(III) and its temperature dependence is reported and a hole-burning mechanism is proposed. This is the first report of non-photochemical hole-burning in the 2 E← 4 A 2 transition of chromium(III) in a crystal.
