摘　　要：用高温固相法合成Sr2Al6O11:Eu2+,Dy3+蓝色发光材料,研究了合成温度、保温时间、B2O3加入量对该材料物相组成和发光性能的影响。结果表明,只有在掺入一定量的B2O3(5%~15%)的条件下,通过控制温度(1000℃~1150℃)和保温时间(1h^2h)能够合成Sr2Al6O11:Eu2+,Dy3+蓝色发光材料。Sr2Al6O11：Eu^2＋,Dy^3＋ blue light-emitting phosphor was prepared by high-temperature solid state reaction technique.The effect of sintering temperature,B2O3 and holding time on the phase of luminescent material and the luminescent spectra of Sr2Al6O11 at room temperature were investigated.The results show that the sample of blue（460nm） light-emitting Sr2Al6O11 can be made only by adding a certain amount of B2O3（5%~15%） and by controlling the temperature（1000℃-1150℃） and the holding time（1h-2h）.
