黄色荧光粉，通过X射线衍射仪、扫描电镜、激光粒度仪、荧光光谱仪对荧光粉的结构、形貌和光学性能进行了表征。结果表明，1200~1300℃温度下生成-Ca

SiO

，在1350~1500℃下生成-Ca

SiO

，Al

和Ce

的掺入未改变Ca

SiO

的结构。在1450℃下合成的-Ca

SiO

∶0.5%Ce

，4%Al

样品的相对发光强度最强。在450nm激发下，在565nm处存在一个宽带发射峰，主要源于Ce

的5d

7/2

和5d

跃迁。荧光粉受热影响较大，在450nm激发下，样品在475K时的发光强度降为室温的63%。监控波长为565nm时，Ce

Abstract

A series of -Ca

SiO

yellow phosphors were prepared by high temperature solid-state reactions. The structure

morphology and optical properties of the phosphors were characterized by X-ray diffractometer

scanning electron microscope

laser particle size analyzer

and fluorescence spectrometer. The results show that -Ca

SiO

and -Ca

SiO

samples form at 1200~1300℃ and 1350~1500℃

respectively. The structures of Ca

SiO

don't change with Al

and Ce

doping. The luminescence intensity of -Ca

SiO

: 0.5%Ce

4%Al

calcined at 1450℃ reaches the maximum. Under the excitation of 450 nm

a broad band emission centered at 565 nm is observed

which mainly corresponds to 5d

7/2

and 5d

5/2

transitions of Ce

. The luminescence intensity of phosphor is influenced by temperature

and it decreases by 37% as the temperature increases from room temperature to 475 K. The decay curves of Ce

can be fitted as the single exponential function. The fluorescence lifetime of the phosphor is 104.2 ns

which is basically consistent with the transition types as well as ionic valence of Ce
