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.
