摘要

采用Pechini溶胶-凝胶法制得纳米级CaWO

荧光粉

通过X射线衍射图、扫描电镜和发射光谱对其形貌和发光性能进行了研究

结果表明750℃条件下所得样品为纯相CaWO

晶体

在X射线激发下发射峰位于420nm

与感蓝胶片的光谱灵敏度匹配良好。其粒径在纳米量级且粒度分布集中是该方法所得CaWO

荧光粉的突出优点。将此荧光粉制成X射线增感屏并与市售同类产品相比

该增感屏可使感光片的成像质量显著提高。

Abstract

CaWO

nano-crystal phosphor was prepared by a Pechini sol-gel process. X-ray diffraction

scanning electron microscope and photoluminescence spectra were used to characterize the resulting phosphor powders. The results indicate that the phosphor prepared at 750℃ is with pure lattice phase

its emitting peak is at 420 nm and mainly consists of globose particles with an average grain size of about 100 nm. Compared with commercial X-ray intensifying screen the images of X-ray film matched with this novel intensifying screen have higher contrast and resolution.
