The method involves plotting the emission polarization ratio against the absorption polarization ratio of single nano-emitters. Using Monte Carlo simulation, we show that these plots depend sensitively on the aspect ratio of the dipole shape. For example, the so-called 3D\u20132D dipole combination, that is, \u03bc\n                    <jats:sub>ab<\/jats:sub>\n                    of radius ratio 1:1:1 and \u03bc\n                    <jats:sub>em<\/jats:sub>\n                    of ratio 1:1:0, would give rise to a vertical line plot.
