摘要：
通过冷凝源产生自由的碱金属纳米颗粒，使其通过可调节温度范围的热化管，并通过可调光进行光电离。高稳定性的粒子通量和自动数据采集程序使能够高效地收集光电离产率曲线。对数据进行仔细拟合，使其符合通用的福勒函数，使得能够获得纳米颗粒的光电离能，并由此得到金属的工作函数，精度约为0.2%。实验装置、纳米颗粒热化率以及光电离阈值分析均进行了详细描述。使用超纯且温度可控的气相纳米颗粒有助于分析电子性质，如工作函数，以及其与热晶格动力学的相互作用。
英文摘要：
A beam of free alkali metal nanoparticles is produced by a condensation source, passed through a thermalizing tube adjustable over a broad temperature range, and ionized by tunable light. High stability of the particle flux and an automated data acquisition routine allow efficient collection of photoionization yield curves. A careful fit of the data to the universal Fowler function makes it possible to obtain nanoparticle ionization energies, and from those, the metal work functions, with $\sim$0.2% precision. The experimental arrangement, nanoparticle thermalization rates, and ionization threshold analysis are described in detail. The use of ultrapure and temperature-controlled gas-phase nanoparticles facilitates the analysis of electronic properties, such as work functions, and of their interplay with thermal lattice dynamics.
