Abstract
This paper reports a red luminescent material based on a NaLi3SiO4 matrix doped with Mn²⁺ and explores its preparation method and optical properties. The results indicate that Mn²⁺ ions occupy the octahedral coordination site of Na⁺ ions and exhibit red light emission at 677 nm to 698 nm under 428 nm excitation. As the Mn²⁺ doping concentration increases, the emission intensity is enhanced, and the emission wavelength shifts to the red region. The material is synthesized using a high-temperature solid-phase method, sintered at 850°C under a reducing atmosphere for 4 hours. This material exhibits excellent chemical stability and optical properties, making it promising for applications in LED lighting and display technology.
