Figure 3

Absorption measurement of PCF containing a porphyrin thin film deposited on the surfaces of its holes in DMF: (length 50 cm, absorption rescaled to 25 cm) the typical Q-band (559 and 599 nm) is observed along with a new near-IR band (660–930) nm. Numerical simulation is shown in red for a typical charge transfer band. More details can be found in [5].
