摘要:
为实现球形YAG:Eu 3+荧光粉的大规模生产,提出通过超声喷雾热解法制备尺寸均匀的球形YAG:Eu 3+荧光粉。先将含有三种金属离子(Y、Al和Eu)的硝酸盐配置成前驱体溶液,然后利用超声高频谐振器将前驱体溶液转为雾滴,再将前驱体雾滴在管式炉中快速蒸发、脱水,聚拢成球形固体前驱体,最后在900 ℃的管式炉中原位晶化转为YAG:Eu 3+荧光粉。采用X射线衍射(XRD)、扫描电子显微镜(SEM)和能量色散X射线光谱(EDS)对产物的物相、形貌和成分进行分析。结果表明:制备所得产物是纯立方结构的YAG:Eu 3+ 荧光粉,呈现出规则的球形形貌,尺寸分布范围窄(100~300 μm),平均直径为1-59~255 μm;荧光粉直径会随着前驱体摩尔浓度的升高而增大;发光光谱显示,球形YAG:Eu 3+荧光粉在紫外光的激发下,在594 nm和615 nm处表现出典型的红光发射。文章采用的超声喷雾热解法具有连续、可控、产物均匀规律等特点,有望在球形YAG:Eu 3+荧光粉的生产中得到实际应用。
