(INVITED) Revisiting Duffy's model for Sb3+ and Bi3+ in double halide perovskites: Emergence of a descriptor for machine learning
The Duffy's model is reformulated for Sb3+ and Bi3+ in cubic chloro- and bromo-elpasolites with « 0D » perovskite structure. The new equation allows calculating the energy of the first s2 → s1p1 electron transition from crystal structure data. The Stokes shift pertaining to the Sb3+ emission in...
