Figure 6

(a–f) Photographed images of the as developed and physically scraped FPs up to 5 cycles, which were visualized using LZOT:NH4Cl (4 wt. %) NPs under UV 254 nm light; (g) Gray scale pixel profiles in the white box region of the (a–f), showing distinct ridges and furrows due to excellence binding of the NPs over LFPs surface; (h and i) 3D interactive plots of the FPs before and after abrasion; RGB photographs of the visualized FPs under UV 254 nm light irradiation (j and k) before chemical treatment and (j’ and k’) after abrasion; (l) Pixel profiles in the white box region of the (j, j’, k, k’); Photographed images of the FPs developed using optimized NPs on the glass surface followed by powder dusting technique under (m–r) UV 254 nm (s–x) UV 365 nm light irradiation with different time periods (0–5 h) (Scale bar: 5 mm). Figures (h and i) are generated using ImageJ software 1.8.0_172 (https://imagej.nih.gov/ij/download.html version).
