[Preparation and characterization of SrS : Eu, Sm phosphor].
In the present paper, SrS : Eu, Sm phosphors for the broad frequency infrared up-conversion were prepared. XRD analysis indicates that the SrS : Eu, Sm samples calcined at 1 100 degrees C for 1 h exhibit good luminescence properties and they are face-center cubic structure of SrS. Excitation spectrum reveals that the samples can be excited by ultra violet and visible light. Fluorescence spectrum of the samples is composed of four emission peaks at 567 nm, 589 nm, 602 nm and 648 nm respectively. Infrared photo-stimulation luminescence spectrum is a broad-band spectrum peaking at about 595 nm. Infrared response range of the samples is mainly between 800 and 1 400 nm.
