Abstract The gold (Au)/cinnamon (Ci) nanocomposite particles (Au-Ci NCPs) were prepared via the pulse laser ablation in liquid (PLAL) technique to customize their fluorescence (FL) characteristics. The morphology, structure and photoluminescence (PL) properties of these NCPs were determined. These ultra-sensitive NCPs (organic-inorganic) with the large surface area revealed a significant fluorescence enhancement and improved surface plasmon resonance (SPR) absorption. The PL spectra of the NCPs showed a prominent stable peak at 436.95 nm with FWHM≈52.87 nm. The observed improvement in the optical properties and chemical structure of the synthesised NCPs are affirmed to be greatly favorable for biomedical applications. Compared to the conventional synthetic drugs, the proposed nontoxic, chemically inert and eco-friendly NCPs with improved FL attributes are expected to be beneficial towards the Au-Ci NCPs enhanced FL-based drug developments.

脉冲激光烧蚀金-肉桂纳米复合材料的定制荧光特性

摘要 通过液体脉冲激光烧蚀 (PLAL) 技术制备了金 (Au)/肉桂 (Ci) 纳米复合颗粒 (Au-Ci NCPs),以定制其荧光 (FL) 特性。确定了这些 NCP 的形态、结构和光致发光 (PL) 特性。这些具有大表面积的超灵敏 NCP(有机-无机)显示出显着的荧光增强和改善的表面等离子体共振 (SPR) 吸收。NCP 的 PL 光谱在 436.95 nm 处显示出一个显着的稳定峰,FWHM≈52.87 nm。所观察到的合成 NCP 的光学性质和化学结构的改进被证实非常有利于生物医学应用。与传统的合成药物相比,所提出的无毒、
