采用微波共沉淀法制备了一种新型球形绿色荧光粉Sr2P2O7：Ce3+，Tb3+。合成在1000 °C下进行15分钟。研究了样品的相结构、形貌、光致发光性能和热稳定性。在Tb 3+单掺Sr2P2O7荧光粉中共掺杂Ce 3+，由于Ce 3+向Tb 3+的能量传递，Tb 3+的绿色发光强度显著增强。该荧光粉具有良好的热稳定性和（0.258，0.605）的CIE色坐标，是一种潜在的绿色发光材料。微波辅助共沉淀法被认为是简单，快速和有利的，在实现所需的化学计量比和均匀性的前体材料相比，与传统的固态反应路线。
A novel spherical green phosphor, Sr2P2O7:Ce3+, Tb3+was prepared by co-precipitation method using a microwave heating system. The synthesis was performed at 1000 °C for 15 min. The phase structure, morphology, photoluminescence properties and thermal stability were investigated. The photoluminescence intensity of green emission from Tb3+was enhanced remarkably by co-doping Ce3+in the Tb3+solely doped Sr2P2O7phosphor because of energy transfer from Ce3+to Tb3+ions. The novel phosphors have excellent thermal stability and remarkable CIE chromaticity coordinates of (0.258, 0.605), indicating its potential application of green emitting phosphor in lighting field. The microwave-assisted co-precipitation method was found to be simple, rapid and advantageous in achieving the required stoichiometry and homogeneity of precursor materials in comparison with the conventional solid state reaction route.
