摘要

•The vibronic coupling induced luminescence behavior of YAG:Cr3+deep-red transparent ceramics were studied.•The underlying electron-phonon coupling interaction was revealed by simulating PL excitaion spectrum with determing the Huang-Rhys factor values.•The dominant phonon energy involving in the vibronic coupling process was determined to be 57 meV.
