摘　　要：以稀土硝酸盐和硼酸作为原料,采用溶胶-凝胶法在硅底片上通过浸涂合成了YBO3∶Eu3+薄膜。应用X-射线衍射(XRD)、能量色散X射线衍射(EDX)、原子力显微镜(AFM)和荧光分光光谱仪分别研究了其晶体结构、形貌、化学成份和光致发光(PL)性能。结果表明,成功合成了YBO3∶Eu3+薄膜,由平均粒径为100 nm、均方根(RMS)粗糙度为10 nm的YBO+3∶Eu3纳米晶组成,在PL光谱中于588 nm和616 nm处分别呈现出橙色发光峰和红色发光峰,归因于Eu3+掺杂的(5D0→7F1)和(5D0→7F2)能级跃迁。Using rare-earth nitrates and boric acid as starting materials,the YBO3∶ Eu3 ＋thin films were synthesized on silicon substrates by sol-gel method through dip-coating. The crystal structure,morphology,chemical composition and photoluminescence property of the films were explored by X-ray diffraction（ XRD）,Energy dispersive X-ray analysis（ EDX）,atomic force microscopy（ AFM）,and fluorescence spectrophotometer,respectively. The results indicate that the YBO3∶ Eu3 ＋thin films with average grain size of 100 nm and 10 nm root mean square（ RMS） roughness. In PL spectrum,the YBO3∶ Eu3 ＋film exhibits strong orange emission peak at 588 nm and red emission peak at 616 nm respectively due to the（5D0→7F1） and（5D0→7F2） energy level transitions of Eu3 ＋doping.
