Schematic illustration showing the influence of ions doping-pattern and network-structural motifs on energy transfer process between traps and dopants.
(a,b) represent the typical trapping and de-trapping process (AG) (traps (C) → activator (A)), as well as energy transfer process (ET) (activator (A) → activator (B)) in different material system (MSI and MSII), respectively. Hybrid Materials (MSIII) involves a solid-solution to offer the suitable coordination geometry for activators (A) and (B) and realize the cascaded energy transfer (traps (C) → activator (A) → activator (B)).
