摘要

Scintillating materials,which can convert high energy X-ray radiation into visible luminescence [1],are crucial parts of X-ray imaging technology.Since the discovery of X-ray in 1895,scintillating materials have witnessed wild applications in various fields,including security inspection,space exploration,nondestructive detection,and medical diagnostics [2,3].Conventional scintillators are generally large inorganic crystals and can only be grown at high temperature,which significantly increases the manufacturing difficulty and cost.The luminescence of current crystal scintillators is usually limited by lowefficiency or afterglow effects,and is difficult to be tuned cross the visible spectrum.As traditional scintillators have reached their performance limits,exploration of new scintillators has become a crucial topic considering the increased demands of X-ray imaging and detection technology [4-6].
