Scintillators are currently widely used in high energy physics, nuclear physics, nuclear medical imaging, industrial exploration, security inspection and so on. The development of new applications puts forward the new requirements for scintillators, and it is becoming extremely urgent to discover the new scintillators. In recent years, perovskite materials present their advantages in the field of solar cell, light-emitting diode, laser, photodetector, memory and so on, owing to their high carrier mobility, long diffusion distance and continuously adjustable emission wavelength. Therefore, the perovskite-based scintillators have attracted great attention and interest due to their low detection threshold, high light yield, fast attenuation, and tunable emission wavelength. This review article summarizes the crystal structure and luminescence properties of organic-inorganic hybrid perovskite and inorganic perovskite scintillators. In addition, the fundamental application of perovskite scintillators for radiation detection has been discussed. The goal of this review article is to introduce the recent advances and development in perovskite scintillators, and a particular focus is given on the challenges and perspectives for their enormous potential application in nuclear medical imaging and radiation detection.
