Distribution of the 69 [Ne v]-selected Type 2 AGN in the [Ne v]l˜ine luminosity vs. redshift plane. The 23 objects detected in the X-rays are marked with a cross. The black dashed lines show the boundaries of the three bins used in the computation of the [Ne v] luminosity function. A total of 50 AGN fall in these three luminosity bins. The blue dashed curve shows the [Ne v] flux limit (in units oferg cm^-2 s^-1) of the zCOSMOS survey.
