摘　　要：制备了CaS,Se:Eu红色DCEL屏.在CaS:Eu中掺入少量Se可以改进DCEL性能.研究了Pb对CaS:Eu的影响.通过发射、激发光谱及衰减的测量,认为Pb²⁺敏化了Eu²⁺.与常规的CaS:Eu相比,CaS:Eu,Pb的DCEL效率和寿命都明显提高了.CaS,Se: Eu red DCEL panels are prepared. Mix a small amount of Se to CaS ?Eu can improve DCEL properties. The effect of Pb on CaS : Eu is studied,through measurement of emission, excitation spectra and decay time,it is suggested that Eu2+ is sensitized by Pb2+. Compared with the conventional CaS: Eu, the DCEL efficiency and lifetime of CaS: Eu, Pb has been obviously increased.
