Photoluminescence of Eu2+-Doped Strontium Cyanamide: A Novel Host Lattice for Eu2+
Eu2+-doped SrCN(2) with different Eu2+ contents were prepared by a high-temperature solid-state reaction under NH(3) atmosphere. SrCN(2) has an energy gap of 4.56 eV by the reflection spectra. The photoluminescence spectra of SrCN(2):Eu2+ at different temperatures were measured. The results show that Eu2+-doped SrCN(2) 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 SrCN(2) has a low quenching temperature.
