摘要：Eu2+-doped SrCN2 with different Eu2+ contents were prepared by a high-temperature solid-state reaction under NH3 atmosphere. SrCN2 has an energy gap of 4.56 eV by the reflection spectra. The photoluminescence spectra of SrCN2:Eu2+ at different temperatures were measured. The results show that Eu2+-doped SrCN2 shows a broad band emission with a peak at 610 nm when it is excited by 350-520 nm at 77 K. With the temperature increasing, the emission intensity decreases remarkably, indicating that Eu2+-doped SrCN2 has a low quenching temperature.
