Cesium tungsten bronzes (CsxWO3), as functional materials with excellent near-infrared shielding properties, demonstrate significant potential for applications in smart windows. However, traditional synthesis methods, such solid-state reactions and solvothermal/hydrothermal approaches, typically require harsh conditions, including high temperatures (above 200 °C), pressure, inert atmospheres, or prolonged reaction times. In this study, we propose an optimized microwave-assisted solvothermal strategy that significantly reduces the severity of conditions through precise parameter control. When benzyl alcohol was employed solvent, CsxWO3 nanoparticles could be rapidly synthesized within a relatively short duration 15 min at 180 °C, alternatively obtained 2 h low temperature 140 °C. when anhydrous ethanol, which is cost-effective environmentally friendly, substituted alcohol, successful also achieved °C h. This method overcomes limitations high-pressure systems, achieving efficient crystallization under low-temperature ambient-pressure while eliminating safety hazards improving energy efficiency. The resulting retain performance visible-light transparency, providing innovative solution safe, rapid, controllable nanomaterials.

Localized Surface Plasmon Resonances of AgAl Alloy Nanoparticles Self-Organized by Annealing of Ag/Al Bilayer Films

Photonics, Journal Year: 2024, Volume and Issue: 11(8), P. 713 - 713

Plasmonic applications have traditionally relied on noble metals such as gold (Au) and silver (Ag) for their excellent plasmonic performance in the visible near-infrared spectrum. However, these are costly, scarce, limitations low stability interband transition losses, which restrict spectral range. To address issues, alternative materials been explored. One material is aluminum (Al), inexpensive, abundant, exhibits remarkable properties UV region well wide tunability. Al also compatible with complementary metal–oxide semiconductor (CMOS) fabrication processes very stable due to its ultrathin native oxide layer. Alloying different can combine advantageous properties, resulting enhanced tunable optical characteristics. This study investigates LSPR of AgAl alloy nanoparticles grown after annealing precursor bilayer films. Interestingly, LSPRs were observed some cases as-deposited bilayers. The experimental results complemented simulations conducted via rigorous coupled-wave analysis (RCWA) method. investigated could be potentially useful energy harvesting or color printing.
