Abstract This study explored linear dose-responses of nano-graphene oxide (GO) using quantitative percent transmittance values in FTIR spectroscopy. First, the samples containing nano-graphene oxide powder were gamma-irradiated in the range of 0–80 kGy. Immediately after the irradiation, the samples underwent various tests including HRTEM and FTIR for characterization purposes. The primary results indicated that depending on the dose, gamma-rays could induce different defects and breaks in the irradiated samples. After the qualitative and quantitative analyses, dose-responses with high degrees of linearity (R2 > 0.99) were found in the analysis of the quantitative values of percent transmittances in different FTIR wavenumbers ranging from 1430 to 1450 cm−1. In this study, the FTIR analysis was successfully done for the first time to achieve the study objectives, and it can be potentially applied for larger dose ranges.

γ 辐照氧化石墨烯中线性剂量响应的分析：FTIR 分析能否被视为检查碳纳米结构中线性剂量响应的新方法？

摘要 本研究使用 FTIR 光谱中的定量百分比透射率值探索了纳米氧化石墨烯 (GO) 的线性剂量响应。首先，含有纳米氧化石墨烯粉末的样品在 0-80 kGy 范围内进行伽马辐照。辐照后立即对样品进行各种测试，包括用于表征目的的 HRTEM 和 FTIR。初步结果表明，根据剂量的不同，伽马射线会在辐照样品中引起不同的缺陷和断裂。在定性和定量分析后，在 1430 到 1450 cm-1 范围内的不同 FTIR 波数的百分比透射率定量值的分析中发现了具有高度线性（R2 > 0.99）的剂量响应。在这项研究中，
