Realization of ZnO microrods and Ag nanoparticles on glass and Si substrates by magnetron sputtering and near band edge photoluminescence enhancement from the exciton-plasmon system

ZnO Matrices as a Platform for Tunable Localized Surface Plasmon Resonances of Silver Nanoparticles

“…The secondary peaks are attributed to higher-order plasmonic resonances, due to the presence of ZnO, which has a high refractive index value. Due to disorder and non-uniformities of the grown nanoparticles, those higher-order resonances were smoothened in our experimental results, resulting in broader absorbance curves [39], as illustrated in Figures 3 and 6. Lastly, UV-Vis spectra from the experimental data showed that ZnO caused a notable increase in absorbance around 3.3 eV.…”

“…The integration of Ag nanostructures in ZnO, which exploits the surface plasmon resonance phenomenon induced by them, has been widely employed to enhance the intrinsic properties of ZnO. Numerous studies have reported that Ag/ZnO nanocomposites demonstrate improved optical and electronic properties, suggesting their potential for use in photocatalysis [23,[26][27][28][29][30], sensing [31][32][33][34], solar cells [35,36], optoelectronics [26,[37][38][39] and antimicrobial [40,41], antibacterial [42] and anticancer [43,44] applications. Clearly, diverse fabrication methods apply to this nanocomposite, as previously outlined in the references for net ZnO and noble metallic NP synthesis, as well as described in [23,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40][41][42][43][44].…”
