Abstract Crystal defects such as cracks, inclusions, dislocations and voids in organic crystal caused impurity occlusion, product quality degradation, and reduced optical and mechanical properties. Crystals that contained a large number of defects faced many difficulties in both the post-processing stage and in-service stage of the product. In recent years, it has become a hot spot for researchers of crystallography. In view of the lack of comprehensive reports on the investigation of organic crystal defects, the formation mechanism and types of crystal defects are described. The detection methods and characterization methods of crystal defects are discussed in detail. The regulation methods for reducing the formation of organic crystal defects are reviewed. The application of crystal defects and crystal morphology control methods in explosives, nonlinear optical materials, and crystal properties improvement of semiconductor materials are summarized.
