How the emission from different spatial regions responds to changes in incident power. (a) shows the excitation intensity difference at which there is the greatest relative increase in emission intensity. (b) shows the ‘switch-on’ intensity, i.e. the excitation power at which the emission intensity exceeds the background level. The colour scale indicates the incident power (μW).
