Fig. 5. Dependence of light emission responses of the Ru(bpy)3Cl2, Ru(bpy)3(PF6)2, Ir(diFppy)2(bpy)PF6, and DPA gels at various low operating frequencies (≤30 Hz) and voltage conditions. The sequential and simultaneous emissions are denoted as 
and 
, respectively. (a) A sample of the Ru(bpy)3Cl2 gel exhibiting both sequential and simultaneous emission. (b) A sample of the Ru(bpy)3(PF6)2 gel exhibiting both sequential and simultaneous emission at high operating frequencies and voltages. (c) A sample of the Ir(diFppy)2(bpy)PF6 gel showing only sequential emission. (d) A sample of the DPA gel showing sequential emission except at very low operating frequencies (1 Hz).
