“…Noble metal nanoparticles (NPs) exhibit pronounced light absorption due to the phenomenon of localized surface plasmon resonance (LSPR) [1], which has garnered significant attention in diverse research fields and applications, encompassing interfacial catalysis [2][3][4][5][6][7], bioimaging [8][9][10][11][12][13], and hyperthermia treatment [14][15][16][17][18][19]. The excitation of plasmons within these nanoparticles is induced by the interaction between incident light and the free electrons residing in the metal, thereby initiating a collective oscillation of conduction electrons within the NPs [20][21][22][23][24].…”

Au nanoparticles (NPs) were designed to be embedded into III-V semiconductors to form Au/GaAs Schottky heterostructures, which were used as top-modified cover layers for quantum dot semiconductor saturable absorption mirrors (QD-SESAMs). By harnessing the distinctive localized surface plasmon resonance (LSPR) effect exhibited by Au NPs, a remarkable enhancement in photogenerated carrier concentration is achieved at the heterojunction interface. Consequently, this leads to a significant improvement in the nonlinear optical characteristics of the device. The modulation depth (MD) and saturation fluence of the device are optimized from the initial 2.2% and 16.1 MW/cm2 to 2.8% and 8.3 MW/cm2, respectively. Based on the optimized device, a Q-switched laser has been developed with an impressive output power of 17.61 mW and a single pulse energy of 274.9 nJ. These results unequivocally showcase the exceptional advantages offered by utilizing Au NPs to optimize the nonlinear optical characteristics of III-V semiconductor devices, thereby highlighting its immense potential for practical applications in various fields.

The development of greener methods for the preparation of three‐membered rings has increased in the last decade, not only due to their biological activity, but also by the ring strain of those heterocycles that make them useful precursors of more complex molecules. In this work, the visible‐light‐promoted synthesis and ring‐opening of aziridines and epoxides, reported in the last five years, were reviewed. Both homogeneous and heterogeneous catalysts were discussed and, in addition, the plausible mechanism pathways were highlighted.
