Figure 2

Confocal PL images of a β-phase dot element, patterned by DPN using decalin ink and a dwell time of 20 s, recorded with PL filtered at (a) 440 nm and (b) 415 nm. PL intensity profiles, IPL(λ), obtained by taking a slice through the centre of the dot in the digitized image and presented here before deconvolution, are given in (c) with filtering at 440 nm (red line) and 415 nm (black line+circles). PL spectra acquired from the dot (red line) and the surrounding film (black line+circles) are shown in (d), with the respective intensities at 440 nm set to the average PL intensities measured on/off the β-phase dot in a.
