用高温固相法合成了NaBaPO4结构材料．NaBaPO4是一类常用于荧光粉基质的材料，本实验通过X射线衍射、红外光谱吸收和发射率表征了材料的结构特性和红外辐射性能，发现NaBaPO4具有很好的辐射性能，当掺杂Mg2＋、Ca2＋和Sr2＋后，引起NaBaPO4晶体的金属离子和氧离子的键长改变，使分子间振动改变，发射率改变．其中以NaBa0.85 Mg0.15 PO4的红外辐射性能最佳，8～14μm波段的发射率可达0.924．

NaBaPO4 powder with high emissivity is synthesized by solid state reaction .And infrared radi-ation properties of NaBaPO 4 can be examined by XRD patterns , infrared transmittance spectra and infra-red emissivity.NaBaPO4 powder, when doped with Mg2+, Ca2 +and Sr2+, will change the bond strength of metal ions and oxygen ions .It can also change the lattice vibration and increase the infrared emissivi-ty.Among the materials of NaBaPO4, we found that the NaBa0.85Mg0.15PO4 can reach the emissivity as high as 0.924 at the wave range of 8~14 μm.
