Photo-thermal expansion of a PMMA nanosphere using mid-IR photo-induced force microscopy (PiF-IR)

This dataset contains the raw data associated with our manuscript, 'Photo-thermal expansion of nanostructures in photo-induced force microscopy' by Shohely Tasnim Anindo,1,2 Daniela Täuber,3,4 and Christin David*1,5 1 Institute of Condensed Matter Theory and Optics, Friedrich-Schiller-Universität Jena, Max-Wien-Platz 1, 07743 Jena, Germany2 Abbe Center of Photonics, Albert-Einstein-Straße 6, 07745 Jena, Germany3 Institute of Physical Chemistry, Friedrich-Schiller-Universität Jena, Helmholtzweg 4, 07743 Jena, Germany 4 Leibniz Institute of Photonic Technology, Albert-Einstein-Straße 9, 07745 Jena, Germany 5 University of Applied Sciences Landshut, Am Lurzenhof 1, 84036 Landshut, Germany The raw data were acquired using a VistaScope (Molecular Vista, US) operated in the side-band mode of mid-infrared photo-induced force microscopy (PiF-IR). These data are associated with the experimental part in this manuscript. Details of the data acquisition and processing are described in the Methods section of the manuscript. The dataset is structured in the following: PiF-IR scans of a spherical PMMA nanoparticle with radius R = 50 nm (PMMA NP) at varied illumination power in the resonant condition using the illumination frequency: 1150 cm^-1 PiF-IR scans of the same PMMA NP at varied illumination power in the non-resonant condition using the illumination frequency: 1300 cm^-1 PiF-IR hyperspectral scan of the same PMMA NP over the spectral range 989 - 1349 cm^-1本数据集包含与我们的学术论文《光诱导力显微术中纳米结构的光热膨胀》相关的原始实验数据。 作者：Shohely Tasnim Anindo¹,², Daniela Täuber³,⁴ 与 Christin David*¹,⁵ ¹德国耶拿弗里德里希·席勒大学凝聚态理论与光学研究所，马克斯-维恩广场1号，07743耶拿 ²德国耶拿阿贝光子学中心，阿尔伯特-爱因斯坦大街6号，07745耶拿 ³德国耶拿弗里德里希·席勒大学物理化学研究所，亥姆霍兹路4号，07743耶拿 ⁴德国莱布尼茨光子技术研究所，阿尔伯特-爱因斯坦大街9号，07745耶拿 ⁵德国兰茨胡特应用科技大学，阿姆卢尔岑霍夫1号，84036兰茨胡特 原始数据通过搭载于中红外光诱导力显微术（mid-infrared photo-induced force microscopy, PiF-IR）边带模式下的VistaScope设备（Molecular Vista，美国）采集得到。本数据集对应本文的实验部分，数据采集与处理的详细流程参见论文的方法章节。 本数据集的结构如下： 1. 共振条件下，以1150 cm⁻¹为照明频率，对半径R=50 nm的球形聚甲基丙烯酸甲酯（polymethyl methacrylate, PMMA）纳米颗粒（PMMA NP）开展变照明功率的PiF-IR扫描 2. 非共振条件下，以1300 cm⁻¹为照明频率，对同一PMMA纳米颗粒开展变照明功率的PiF-IR扫描 3. 对同一PMMA纳米颗粒在989–1349 cm⁻¹光谱范围内开展PiF-IR高光谱扫描
