Excitation Density Dependence of Optical Oxygen Sensing in Poly(9,9-dioctylfluorene) Waveguides Showing Amplified Spontaneous Emission

Figure 1

Excitation density dependence of the PL spectra measured in vacuum. A clear ASE band is observed in the spectra for excitation density higher than about 120 μJcm−2.
