以BaCO3、BaF2和H3BO3为原料,按照化学计量比采用高温固相反应法制备出了新型蓝色荧光材料Ba4B11O20F,后通过水热法对其进行二次处理.利用XRD、SEM和荧光光谱仪等对水热处理前后的粉体的物相、形貌和发光性能进行了研究.结果表明:Ba4B11O20F荧光粉在294 nm激发条件下得到的发射光谱中存在三个发射峰分别位于367 nm、402 nm和470 nm处,在紫外灯照射下成明亮的蓝色.通过研究水热工艺中的温度和加水量对粉体荧光强度的影响,得出在加水量为10 mL,恒温温度为110℃条件下获得荧光粉的荧光强度最强,比水热处理前提高了8％.水热二次处理工艺提高了粉体的纯度和结晶度,进而提高了粉体的荧光强度.
