Contact UsDense rutile (Figure 3a) exhibits an exponential decay between ca. 3 and 100 ps with little intensity dependence. The mesoporous rutile film (Figure 3b) exhibits decay kinetics remarkably similar to the dense one. As for anatase, this similarity suggests that surface state recombination is not a key cause of charge carrier recombination.
