The rising demand for radiation detection materials in many applications has led to extensive research on scintillators.
Recently, Xiaogang Liu, Yu Wang and other members of SZU-NUS Collaborative Innovation Center for Optoelectronic Science and Technology published an original research article entitled “All-Inorganic Perovskite Nanocrystal Scintillators” in journal Nature (IF = 41.577) in collaboration with Wei Huang from Northwestern Polytechnical University and Huanghao Yang from Fuzhou University.
This article describes experimental investigations of a series of all-inorganic perovskite nanocrystals comprising caesium and lead atoms and their response to X-ray irradiation. These nanocrystal scintillators exhibit strong X-ray absorption and intense radioluminescence at visible wavelengths. The article also shows that these colour-tunable perovskite nanocrystal scintillators can provide a convenient visualization tool for X-ray radiography, as the associated image can be directly recorded by standard digital cameras and also demonstrates their direct integration with commercial flat-panel imagers and their utility in examining electronic circuit boards under low-dose X-ray illumination.
