Abstract

A new phosphor CaSnO3: Yb3+ was synthesized by a traditional solid-state reaction and the luminescent properties were investigated. The phosphors are well crystallized at 1200 °C. The excitation and the emission spectra show the characteristic broad of the Sn2+ ion and the X-ray photoelectron spectroscopy demonstrate the existence of Sn2+ ions caused by the doping of Yb3+ ions. The CaSnO3: Yb3+ phosphor showed a typical afterglow behavior when the UV source was switched off. Thermal simulated luminescence study indicated that the persistent afterglow of CaSnO3: Yb3+ phosphor was generated by the suitable electron or hole traps which were resulted from doping the calcium stannate host with rare-earth ions (Yb3+).
