液相剥离是一种强大的和可扩展的技术，以生产无缺陷的单层和少层石墨烯。然而，样品通常是多分散的，并且对尺寸和厚度的控制具有挑战性。值得注意的是，缺乏测量尺寸和厚度的高通量技术。在这项工作中，我们测量了不同横向尺寸（90
Liquid phase exfoliation is a powerful and scalable technique to produce defect-free mono-and few-layer graphene. However, samples are typically polydisperse and control over size and thickness is challenging. Notably, high throughput techniques to measure size and thickness are lacking. In this work, we have measured the extinction, absorption, scattering and Raman spectra for liquid phase exfoliated graphene nanosheets of various lateral sizes (90
