摘要:

掺杂稀土元素的发光材料具有优异性能,通过溶胶-凝胶法制备了2种晶型钛酸锶材料(钙钛矿结构和层状钙钛矿结构),并制备以钛酸锶为基质掺杂稀土离子Sm3+的凝胶前驱体,高温煅烧前驱体得到发光性能优异的发光材料粉体。试验对制备的红色荧光粉的结构、形貌和性能进行表征,并得出最佳钐掺杂量。

Abstract:

The luminescent materials doped with rare earth have outstanding performance.So 2 crystal types of strontium titanate base materials(perovskite structure and layered perovskite structure) were synthesized by sol-gel method.And the precursor with strontium titanate base and doped with the rare earth ion Sm3+ was prepared,and calcined at high temperature to obtain the luminescent material powder with improved luminescence.The structure,morphology and performance of the prepared red phosphor were characterized in the test and the optimum doping amount of samarium was obtained.
