It is a study of the microstructure of ancient materials that will be investigated using catholuminescence microscopy. The importance of
this method is in the identification of historical materials based on the observation and analysis of structures that are not observable in other
methods of microscopic studies. The cathodoluminescence properties of materials and their microscopic observation can be used both in the analysis of production technology and concerning the historical origin of materials. This study examined several samples of prehistoric and historic ceramics from Haft Tappeh, ChoghaZanbil, Persepolis and some stones from the Pasargadae foundation. The thermal regime and temperature of the pottery are determined based on the type of crystalline material in the pottery matrix and the phase changes during cooking, to interpret the technology and origin of the pottery. On the other hand, identification of the luminescence characters created by the minerals in the carbonate rocks of the Pasargadae and their similarity to the possible mineral rocks in the area (Abolverdi Mine), can provide useful information in identifying the origin of the rocks used in this building. To determine the microscopic applications of catholuminescence, all the materials studied were first studied using standard laboratory methods, such as optical microscopy, X-ray diffraction and thermal studies to determine the phase changes of crystalline and mineral phases and determine the firing temperature of the pottery. Complementary results based on catholuminescence microscopy indicate the observation of the process of crystalline changes and the heating of the pottery matrix based on the type and quality of the raw materials used and their similarities and differences in the pottery texture. Also, the observation of the microstructures of the rocks based on their mineralogy and microfossils which were contained in it and are not normally visible, provides useful information about the similarity of the types of stones used in the construction of Pasargadae with the rock outcrops from the mines around Pasargadae.
