摘要
用燃烧法制备出了绿色掺Tb3+荧光粉,研究了助熔剂的量,光敏剂铈与激活剂的比例,硝酸镁的量,温度等因素对发光亮度的影响,其最佳合成条件是初始反应温度600℃、铈铽的物质的量比2∶1、硼酸的量为0.05mol。测定了荧光粉的激发光谱和发射光谱。
The green phosphor doped Tb3+ has been pr epared by combustion method It was researched that influence of the amount of fusing agent, the ratio of sensitizer Ce3+ and activator Tb3+, the amount of aluminum nitrate and magnesium nitrate, temperature on luminescence intensity The best of prepared condition is the original reaction temperature at 600℃,the molar ratio Ce3+/Tb3+=2/1, the boric acid content 005mol/mol The excitation spectrum and emission spectrum have been determined
