Making photonic sintering of metal nanoparticles, a viable nanomanufacturing process for printed electronics requires an understanding of all of the parameters that lead to variability in the photonic sintering process. This article examines the effects of variability in the exact location of nanoparticles within a packing on the thermo-optical properties of the assemblies. Multiple discrete-element method (DEM) simulations for various nanoparticle packing configurations are created, and the absorption, scattering, and extinction cross sections for each of these configurations are calculated. The results of these simulations are then validated using experimental measurements on actual nanoparticle packings and analyzed to determine how uncertainty in the initial nanoparticle packing configuration translates into variances in its calculated thermo-optical properties. Overall, it was found that simulations matched very well with the absorptivity measurements between 400 and 800 nm wavelength light illumination that uncertainty in the initial nanoparticle configuration resulted in about a 15%–25% variance in the thermo-optical properties of the nanoparticle packings for the analyzed cases.

等离子纳米粒子包装中的变异性对光学散射和消光截面的影响
进行金属纳米粒子的光子烧结是一种用于印刷电子的可行的纳米制造工艺,需要了解导致光子烧结工艺可变性的所有参数。本文研究了填料中纳米颗粒确切位置的可变性对组件热光学性能的影响。创建了用于各种纳米颗粒堆积结构的多重离散元素方法(DEM)模拟,并计算了每种结构的吸收,散射和消光截面。然后,使用对实际纳米颗粒填充物的实验测量来验证这些模拟的结果,并进行分析,以确定初始纳米颗粒填充物结构的不确定性如何转化为其计算的热光学性质的差异。总的来说,发现模拟与400至800 nm波长的光吸收之间的吸收率测量非常吻合,初始纳米颗粒配置的不确定性导致纳米颗粒填料的热光学性能在大约15%至25%的范围内变化。分析的案例。
