Scintillation based X-ray detection has received great attention for its application of radiation detectors for radiation exposure monitoring, security inspection (scan your luggage in the airport), space exploration, and medical imaging (images of your teeth) [ 1 ]. In recent years, scintillators receive extensive attention because of their ability to convert ionizing radiation into visible photons, and hence it is a common type of X-ray detector. While various types of materials have been used for X-ray scintillators, there are still many issues and limitations to existing organic and inorganic scintillation materials, for example, laborious environments are required for the preparation of inorganic c rystals because of their hygroscopic nature, anisotropic scintillation of organic crystals, low light yields in plastics, and so on. Hence, searching for high-performance scintillation materials and its low-cost, are still of great scientific and practical interest [ 2 ].  Developin...
