Ultrafast Spectroscopy Study on T4 Organic Dye-sensitized Films
Excited-state processes in T4 organic dye-sensitized Al
2
O
3
and TiO
2
films were studied by femtosecond transient absorption spectroscopy and femtosecond time-resolved photoluminescence dynamics based on up-conversion method. By multiexponential analysis
we obtained the electron injection efficiency of 93% in T4 dye-sensitized TiO
2
film. In addition
we further got the electron injection rate of 1.17 ps
-1
in the T4 dye-sensitized TiO
2
film by a static inhomogeneous electronic coupling model.
