摘要
本研究探讨了在去离子水中通过脉冲激光烧蚀合成锗纳米粒子(Ge NPs),以用于纳米光子学和光电应用。本研究深入探讨了激光脉冲能量对 Ge NP 特性的影响,特别强调了尺寸控制和光学特性。我们的研究结果表明,随着激光脉冲能量的增加,Ge NP 的尺寸明显减小,从最初的 30 纳米减小到 20 纳米。值得注意的是,我们观察到合成的 Ge NP 发出的蓝色荧光与尺寸有关。这种可控合成为光电和传感应用带来了希望。这项研究为精确合成 Ge NP 提供了有价值的见解,并强调了它们引人入胜的光学特性,为先进的纳米光子器件铺平了道路。
Optical Properties of Germanium Nanoparticles Prepared by Laser Ablation
The synthesis of germanium nanoparticles (Ge NPs) through pulsed laser ablation in deionized water is investigated for Nanophotonics and optoelectronic applications. This study delves into the influence of laser pulse energy on Ge NP properties, specifically highlighting size control and optical characteristics. Our findings reveal a significant reduction in Ge NP size, from an initial 30 nm to 20 nm, as the laser pulse energy increases. Notably, we observed size-dependent blue luminescence from the synthesized Ge NPs. This controlled synthesis holds promise for optoelectronics and sensing applications. The study provides valuable insights into precise Ge NP synthesis and underscores their intriguing optical properties, paving the way for advanced Nanophotonic devices.
