There is no sharp classification between different methods. The materials should be characterized after synthesis to ensure the successful synthesis of the target materials and confirm their properties. There are a wide number of analytical methods used for materials characterization. The characterization techniques can be classified based on their principles, usage, and information received from their analysis (Figure ). Data interpretation is tricky and sometimes misleading. Thus, experience is highly required to avoid misinterpretation. The data interpretation should be supported by other techniques. Most of these techniques can be also used to evaluate the performance of the material for specific applications. The standard recipe for the materials characterization should include the answer to the main questions of the study including these questions; size?; and what are the physical properties? Material is different from compounds or molecules. Thus, it is a difficult task to fully understand the materials with a limited number of characterization techniques. More techniques are highly desirable to decrease the gap that exists in material characterization. Simply, do more analysis to understand the material's properties.
