You can get the Purcell factor from the dipole source, which is dipower_radiated_power/source_power_in_homogeneuous_material

source_power_in_homogeneuous_material can be obtained by sourcepower:

sourcepower - Script command

dipolepower - Script command

Understanding dipoles in non-homogeneous materials

Purcell factor of a microdisk

You can also get the radiation spectrum from the point time monitor.
