“…Bigger particles, however, are observed after the second pulse resulting in intense LSPR peak (Figure 4c, green solid line). The lower photon energy at 248 nm and the fact that the pulse duration is shorter than the time required for Ostwald ripening in a cold environment [57,58] (the process is indeed relatively cold because the 248 nm beam is not absorbed by the AlN matrix due to its high fundamental gap) allows for the Ostwald ripening process to take place in two steps: dissolution of particles for the first pulse and reforming of bigger particles close to the surface for the second pulse. Finally, the optical reflectivity spectrum for five pulses (Figure 4c, blue solid line) exhibits a broad LSPR band, resembling the broadening of the LSPR band for two applied pulses at 193 nm (Figure 4b, green solid line), but blue-shifted compared to the band for two pulses of 193 nm indicating a surrounding medium that is less optically dense than AlN (e.g.…”

“…Among the various categories of materials used for coatings, nanocomposites consisting of noble metal inclusions [1][2][3][4][5][6] are of substantial importance due to their particular functionalities that originate from the nanometric dispersion of the metallic phase and offer exceptional potential to control their mechanical behavior [7][8][9], and open perspectives for a variety of applications such as catalysis [10][11][12], biocompatible surfaces [13][14][15][16][17], solar harvesting [18][19][20], and foremost plasmonics [21][22][23][24][25][26][27][28][29]. In particular, the ability of controlling the optical performance via the morphology of the embedded plasmonic nanoparticles (NPs) into the coating and their localized surface plasmon resonance (LSPR) offers also great potential for decorative and ophthalmic coatings [30][31][32][33].…”
