(a) FM images of microboxes created by focused laser scanning, with laser power of (i) 2.7 mW, (ii) 4.9 mW, (iii) 5.3 mW, (iv) 18.8 mW, (v) 23.9 mW, (vi) 57.8 mW, (vii) 72.9 mW and (viii) 105.2 mW. (b) PL spectra of the microboxes (i-viii) and that irradiated at 141.8 mW. (c) A plot of the integrated PL intensity (400 nm–600 nm) versus laser power, divided into the region I, II, IIIA and IIIB.
