Abstract

Chinese purple (CP), an ancient traditional pigment, represents the rich cultural and scientific heritage of an ancient civilization. To achieve high-purity CP pigment in a more economical and efficient manner, we synthesized CP using a low-temperature hydrothermal route. Interestingly, we observed the emergence of an emission peak at 894 nm in CP under irradiation at λ_ex = 650 nm. Additionally, it was noted that the CP powder exhibited a significant photothermal effect when exposed to near-infrared light irradiation. A photothermal conversion efficiency of 19% was achieved in the CP pigment. This study not only sheds light on the enigmatic nature of this ancient pigment but also highlights its potential as a critical photothermal conversion material.

实现了传统紫外光（BaCuSi2O6）颜料的高光热转换效率

中国紫色（CP）是一种古老的传统颜料，代表着一个古老文明丰富的文化和科学遗产。为了更经济高效地获得高纯度CP颜料，我们采用低温水热法合成了CP。有趣的是，我们观察到在λex = 650 nm的辐照下，CP在894 nm处出现了一个发射峰。此外，CP粉末在近红外光照射下表现出明显的光热效应。CP颜料的光热转换效率为19%。这项研究不仅揭示了这种古老颜料的神秘性质，而且强调了它作为一种关键光热转换材料的潜力。

期刊介绍： Archaeometry is an international research journal covering the application of the physical and biological sciences to archaeology, anthropology and art history. Topics covered include dating methods, artifact studies, mathematical methods, remote sensing techniques, conservation science, environmental reconstruction, biological anthropology and archaeological theory. Papers are expected to have a clear archaeological, anthropological or art historical context, be of the highest scientific standards, and to present data of international relevance. The journal is published on behalf of the Research Laboratory for Archaeology and the History of Art, Oxford University, in association with Gesellschaft für Naturwissenschaftliche Archäologie, ARCHAEOMETRIE, the Society for Archaeological Sciences (SAS), and Associazione Italian di Archeometria.
