a,b, Heat maps of a device containing only the sensitizer PdPQ4NACA (a) and a device with NODIPS-An (b). Reference lines indicate the areas integrated for the kinetic traces. c, Kinetic trace for the region of 470–490 nm tracking the GSB for the sensitizer with and without NODIPS-An. Solid lines are triexponential fits of the kinetic traces with the resulting lifetimes and weights reported in the figure. d, Kinetic traces of PdPQ4NACA phosphorescence.
