摘要：

A review is given of recent studies on SrS-based phosphors that are being developed for improving the color properties of electroluminescent (EL) displays. A dramatic improvement in the crystallinity, photoluminescence and EL performance for SrS : Cu was achieved by vacuum annealing under a sulfur flow. The two-component SrS : Cu,Ag phosphor has been shown to exhibit an efficient blue color, thus combining the superior excitation properties of Cu with the strong blue radiative properties of Ag. Additionally, studies in improving the EL efficiency by enhancing grain growth and by co-doping are discussed in a new green phosphor, SrS : Mn, and a preliminary results are presented for SrS : Eu.
