red phosphor for high color rendering LED was prepared using Sr

N as raw materials by high pressure nitrogenize sintering method. The effects of Sr

proportions and different fluxes on morphology and luminescence properties of phosphors were analyzed by scanning electron microscope(SEM)

X-ray diffraction(XRD)

excitation and emission spectrum. XRD patterns and XRD Rietveld refinement showed that the 1.3 times Sr

material has better luminescent intensity and more pure phase state. The influence of the chlorides and fluorides fluxes on the morphology and luminescent properties was also discussed. NH

F and LiCl had better fluxing effect and they were selected as mixed fluxes. The effects of different proportions of the mixed fluxes on the luminescent properties of the phosphors were studied in detail. The experimental results showed that the phosphor had the better particle morphology and the luminescent intensity was increased by nearly 4 times when the combination ratio of NH

F and LiCl was 1:1. White LED(4 000 K) was prepared by combining with (Sr

and GAG535 green phosphor and the results indicated that this LED has higher luminous efficiency and higher

which was more suitable for high color rendering index white LED.
