Data and scripts from: Noninvasive identification of carbon-based black pigments with pump-probe microscopy

Carbon-based black pigments, a widely used class of pigments, are difficult to differentiate with the noninvasive techniques currently used in cultural heritage science. We utilize pump-probe microscopy to distinguish four common carbon-based black pigments as pure pigments, as two-component black pigment mixtures, and as a mixture of a black and a colorful pigment. This work also demonstrates that even nominally "homogeneous"pigments present remarkable, and useful, heterogeneity in pump-probe microscopy.碳基黑色颜料作为一类应用广泛的颜料，难以借助当前文化遗产科学领域所采用的非侵入式技术实现区分鉴别。本研究采用泵浦探测显微术（pump-probe microscopy），对四种常见碳基黑色颜料的纯样、双组分黑色颜料混合物，以及黑色与彩色颜料的混合体系均实现了区分鉴别。本研究同时证实，即便名义上为"homogeneous"的颜料，在泵浦探测显微术观测下也会展现出显著且极具应用价值的异质性。
