Abstract:Electron trapping infrared up-conversion material (CaS: Eu, Sm) was prepared with the carbon reducing method (CRM). The reaction mechanism, reducing principle, infrared upconversion mechanism and effect of calcined temperature on the lattice formation of CaS and its optical properties were studied. XRD patterns of the samples indicate that CaS: Eu, Sm is with face-center cubic structure. Excitation spectrum is within the range of 200~600nm. Fluorescence emission spectrum is a broadband spectrum peaking at 567nm, 606nm and 630nm respectively. The peak of the up-conversion emission luminescence spectrum is at 625nm. The wavelength response range of the up-conversion luminescence is located at 800~1600nm.
Keywords:CaS: Eu  Sm  carbon reducing method  infrared up-conversion  electron trapping
