摘 要: 采用微波辅助共沉淀法制备橙红色Zn3(PO4)2: Eu3+, Gd3+发光材料,通过X射线粉末衍射和光谱学对其物相和发光性能进行表征,并探讨Gd3+-Eu3+在Zn3(PO4)2体系中的能量传递过程。研究结果表明,在煅烧温度为900℃时保温15 min即可制备出Zn3(PO4)2: 0.24Eu3+, 0.30Gd3+的橙红色发光材料。Gd3+-Eu3+之间的非辐射能量传递和Eu3+-O2?电荷迁移跃迁的协同作用,提高了Eu3+离子的发射强度。样品在77~423 K的测试温度下,表现出良好的发光热稳定性。

Abstract: Novel orange-red light emitting phosphor Zn3(PO4)2: Eu3+, Gd3+ was synthesized by the microwave-assistant co-precipitation method and we investigated phase and photoluminescence properties by X-ray powder diffraction and spectroscopy. The Gd3+-Eu3+ in Zn3(PO4)2 system in the energy transfer process are also discussed in detail. When the calcination temperature is 900℃ and holding for 15 min, Zn3(PO4)2: 0.24Eu3+, 0.30Gd3+ orange red phosphor can be prepared. The Eu3+ ion emission intensity can be improved via the non-radiation energy transfer between Gd3+-Eu3+ and Eu3+-O2? charge transfer transition synergies. Besides, the novel phosphor showed excellent luminescence properties under the test temperature of 77 K to 423 K.
