[Progress in the research on silicon-nitrogen based phosphor for white LED].

With the rapid development of white LED technology, the traditional YAG : Ce3+ phosphor is difficult to meet the requirement due to the low color rendering and high color temperature. Using ultraviolet chip to stimulate the tri-phosphor has become an effective way for white LED, and it is urgent to develop novel tri-phosphor with high-performance, especially for red light-emitting materials. Silicon-nitrogen based compounds contain the network structure composed of SiN4 tetrahedron, with higher chemical and thermal stability.

[Study on Sr3LiMgV3O12 : Eu3+ single-phase phosphor for white LED].

A novel broadband emission phosphor Sr(3-2x) Li(1+ x) MgV3 O12 : xEu3+ was synthesized by a solid-state reaction method. Then discussed the luminous property under the influence of temperature and doping density of Eu3+, was discussed. X-ray diffraction (XRD), scanning electron microscopy (SEM), and photoluminescence spectra were used to characterize the feature of Sr(3-2x)Li(1+x)MgV3O12 : xEu3+.
