Efficient energy transfer from organic triplet states to Mn2+ dopants for dynamic tunable multicolor afterglow in 1D hybrid cadmium chloride

Tuning Mn 2+ doping in the novel 1D hybrid metal halide enables afterglow color transitions from yellow-green to yellow, orange, and red, resulting from efficient energy transfer from stable organic triplet states to the 4 T 1 level of Mn 2+ dopants.
