摘要

采用水热法制备了中空球形Eu

掺杂CaWO

荧光粉体为结晶度较好、形貌均匀、粒径为4 m的中空球形结构。在395 nm激发下，Eu

的特征发射峰位于591 nm和614 nm处，对应于

和

跃迁。pH=5时所合成粉体在614 nm处的红光发射强度最大。

Abstract

doped CaWO

phosphors were prepared

via

hydrothermal method. The crystal structures

morphologies and luminescence properties of the powders synthesized at different pH values were characterized by X-ray powder diffraction (XRD)

field emission-scanning electron microscopy (FE-SEM) and photoluminescence (PL). The experimental results indicate that CaWO

:Eu

particles are hollow spherical shape with good crystallinity

uniform morphology and the diameter about 4 m when pH of the synthesis solution is higher than 5. Under the excitation of 395 nm ultraviolet light

the emission peaks of CaWO

:Eu

phosphor are around 591 nm and 614 nm

which can be attributed to

transitions of Eu

respectively. The 614 nm red emission of CaWO

:Eu

phosphor is the strongest when pH of the synthesis solution is 5.
