以硼酸、三聚氰胺和葡萄糖为原料，在625°C的常压下制备了发射光谱可调的BCNO荧光粉。XRD、SEM和FTIR结果表明，所制备的复合材料由立方相B2 O3和部分晶态BCNO组成。通过改变葡萄糖的含量和硼酸与三聚氰胺的摩尔比，可以实现发射峰位在510 ~ 560 nm之间的调谐。BCNO荧光粉的衰减过程可用双指数函数拟合，寿命τ 1和τ 2分别与BCNO荧光粉中的碳杂质浓度和其他缺陷有关。
BCNO phosphors with tuneable emission spectra were prepared at 625°C under atmosphere using boric acid, melamine and glucose as raw materials. The XRD, SEM and FTIR results show that the prepared compound is composed of cubic B2O3and partially crystalline BCNO. The emission peak position can be tuned from 510nm to 560nm by changing the glucose contents and the mol ratios of boric acid and melamine. The decay process of BCNO phosphors can be fitted well by double exponential function, and the lifetimes τ1and τ2were correlated with carbon impurity concentration and other defects in BCNO phosphor, respectively.
