利用燃烧法在较低温度（900℃）下按化学计量快速合成发光材料nSrO·7Al2O3：Eu2+（n等于1～10）．讨论Sr2+含量、助熔剂浓度及磷含量对磷光体发光性能的影响，并测定4SrO·7Al2O3：Eu2+的发射光谱、激发光谱、X-射线衍射光谱、粒度分布及比表面积．结果表明：4SrO·7Al2O3：Eu2+主要是碱式铝酸盐SrAl3O5（OH）结构．与高温固相反应比较，燃烧法具有反应时间短、制得的产物相对发光亮度高、粒度小、分布均匀及比表面积大等特点．
The luminescent material nSrO · 7Al2O3: Eu2 + (n is equal to 1 ~ 10) was rapidly stoichiometrically synthesized at low temperature (900 ℃) by combustion method. The effects of Sr2 + concentration, flux concentration and phosphorus content on the luminescent properties of phosphor were discussed. The emission spectra, excitation spectra, X-ray diffraction spectra, particle size distribution and specific surface area of 4SrO · 7Al2O3: Eu2 + were determined. The results show that: 4SrO · 7Al2O3: Eu2 + is mainly aluminate SrAl3O5 (OH) structure. Compared with the solid state reaction at high temperature, the combustion method has the advantages of short reaction time, high luminance, small particle size, uniform distribution and large specific surface area.
