Abstract
A model of 2E to 4T2 tunnelling induced by zero-point vibrations is developed to account for the observed temperature dependence in the photoluminescence spectrum of Cr3+ ions in crystals with small energy separation Delta E=E(2E)-E(4T 2). The model gives good agreement with experimental results for Cr3+ -doped Gd3Sc2Ga3O12, where Delta E=70 cm-1 is smaller than the mean phonon energy h(cross) omega approximately=180 cm-1.
