One-shot-laser-pulse-induced cooperative charge transfer accompanied by spin transition in a Co-Fe Prussian blue analog at room temperature
A one-shot-laser-pulse (6 ns) irradiation converted the electronic state of Na0.68Co1.20[Fe(CN)(6)].3.7H(2)O from Fe-II(S = 0)-CN-Co-III(S = 0) to Fe-III(S = 1/2)-CN-Co-II(S = 3/2) at room temperature. This photochemical reaction was observed only above the power density of 45 mJ pulse(-1) cm(-2), and its quantum yield amounted to about 200%.
