摘要

A new low-temperature synthesis route of the strongly red-emitting Eu ~(2+) activated nitride phosphor CaAlSiN_3 is presented. The fluorides CaSiF_6 and AlF_3 were used as a source of metal ions and Li_3N as a nitrogen source. A KCN/LiCl flux system was employed to lower the temperature of the reaction from 1100 to 750 °C. The course of the reaction was studied by differential thermal analysis, and the product of the reaction was inspected by X-ray powder diffraction and luminescence measurements of CaAlSiN_3:Eu.
