The basic principle of Laser Induced Breakdown Spectroscopy (LIBS) is a new method that uses high-energy laser pulses to form plasma on the surface of the sample to be measured and uses the spectrometer for analysis. Its advantage is that the sample bin is an open type, which can directly put larger samples into it for in situ analysis. At the same time, there is no requirement on the shape, nature and flatness of the samples, and there is no need for complex and time-consuming sample preparation process; Secondly,
To thoroughly practice the principle of international collaboration that is the Belt-and-Road Initiative as advocated by the Chinese President Xi Jinping while promoting the “Belt-and-Road Science, Technology and Innovation Cooperation Action Plan”, China’s Palace Museum and Greece’s Institute of Electronic Structure and Laser of the Foundation for Research and Technology-Hellas (IESL-FORTH) jointly applied for the establishment of the China-Greece Belt-and-Road Joint Laboratory on Cultural Heritage Conservation Technology (Joint Laboratory). Supervised by China’s Ministry of Science and Technology and recommended by China’s Ministry of Culture and Tourism, the application was formally approved in September 2020.
