Abstract

YAG:Ce3+ nanocrystals are promising bio-labeling materials due to their low toxicity and high photostability. It is in demand to efficiently synthesize YAG:Ce3+ nanocrystals of a small size. Pulse laser ablation is an approach to produce nanoparticles directly from bulk materials with the advantages of smaller particle sizes and lower production costs. Here, we present the synthesis of YAG:Ce3+ nanocrystals from bulk crystal using the femtosecond laser ablation method in liquid. Comparing the liquid environment, we demonstrated that the lauryl dimethylaminoacetic acid betain (LDA) aqueous solution is preferred for the formation of smaller-sized YAG:Ce3+ nanoparticles than deionized water due to the attractiveness between the LDA molecules and the YAG:Ce3+ nanoparticles. We also verified that the high laser repetition rate had no effect on the average size of YAG:Ce3+ nanocrystals, where the fragmentation process is saturated under a high laser repetition rate. This study provides a simple and effective method to synthesize small size YAG:Ce3+ nanoparticles by femtosecond laser ablation in liquid.

飞秒激光合成液态 YAG:Ce3+ 纳米粒子

YAG:Ce3+ 纳米晶体具有低毒性和高光稳定性，是一种前景广阔的生物标记材料。目前需要高效合成小尺寸的 YAG:Ce3+ 纳米晶体。脉冲激光烧蚀是一种直接从块状材料中生产纳米颗粒的方法，具有颗粒尺寸更小、生产成本更低的优点。在此，我们介绍了利用飞秒激光烧蚀法在液体中从块状晶体合成 YAG:Ce3+ 纳米晶体的过程。通过比较液体环境，我们证明月桂基二甲基氨基乙酸甜菜碱（LDA）水溶液比去离子水更适合形成较小尺寸的 YAG:Ce3+ 纳米粒子，这是由于 LDA 分子与 YAG:Ce3+ 纳米粒子之间存在吸引力。我们还验证了高激光重复率对 YAG:Ce3+ 纳米晶体的平均尺寸没有影响，在高激光重复率下，碎裂过程达到饱和。本研究提供了一种在液体中利用飞秒激光烧蚀合成小尺寸 YAG:Ce3+ 纳米粒子的简单而有效的方法。

期刊介绍： The Optical Society (OSA) publishes high-quality, peer-reviewed articles in its portfolio of journals, which serve the full breadth of the optics and photonics community. Optical Materials Express (OMEx), OSA''s open-access, rapid-review journal, primarily emphasizes advances in both conventional and novel optical materials, their properties, theory and modeling, synthesis and fabrication approaches for optics and photonics; how such materials contribute to novel optical behavior; and how they enable new or improved optical devices. The journal covers a full range of topics, including, but not limited to: Artificially engineered optical structures Biomaterials Optical detector materials Optical storage media Materials for integrated optics Nonlinear optical materials Laser materials Metamaterials Nanomaterials Organics and polymers Soft materials IR materials Materials for fiber optics Hybrid technologies Materials for quantum photonics Optical Materials Express considers original research articles, feature issue contributions, invited reviews, and comments on published articles. The Journal also publishes occasional short, timely opinion articles from experts and thought-leaders in the field on current or emerging topic areas that are generating significant interest.
