Abstract：Y3Al5O12 (YAG - yttrium aluminum garnet): Sm3+-Bi3+ co-doped luminescent glasses for the white light emitting diodes (W-LEDs) were prepared. The precursor of Y3Al5O12: Sm3+-Bi3+ was synthesized by a chemical co-precipitation method (CPM). The luminescent glasses were obtained with the heat treatment of Ba2CO3 - Na2CO3 - H3PO4 -SiO2 -Al2O3 glass matrix and the precursor of Y3Al5O12: Sm3+-Bi3+ at 1400 C. The influence of the Sm3+ and Bi3+ contents and calcination temperature on the glass luminescent properties was analyzed. Scanning electron microscopy (SEM) results of the inner structure obtained YAG:Sm,Bi fluorescent glasses show that micro particles are distributed homogeneously in the glass matrix, presenting smooth surface and relatively uniform particle size. Luminescent glass can be efficiently excited by ultraviolet (UV) light (400 nm) and emit the strong red light of 602 nm due to the Sm3+ transition of 6H5/2→4D3/2, 6H5/2→6P7/2, 6H5/2→4F7/2, 6H5/2→4I9/2 in excited range and 4G5/2→6H5/2, 4G5/2→6H7/2, 4G5/2→6H9/2 in emission range. The optimum contents of Sm3+ and Bi3+ doped in the YAG: Sm3+-Bi3+ fluorescence glasses are 5% and 2 mol%, respectively, which shows much stronger luminescence intensity. Therefore, the fabricated luminescent glass would have a promising application in the area of white light-emitting diodes.

摘要：采用化学共沉淀法制备YAG前驱体，与玻璃初始材料均匀混合进行煅烧，形成荧光玻璃。通过荧光分光光度计测定YAG:Sm3+,YAG:Sm3+,Bi3+荧光玻璃的激发光谱和发射光谱，研究钐含量、掺杂铋含量、煅烧温度对荧光玻璃发光特性的影响。结果表明：荧光玻璃能有效地被400nm的紫外光激发而发射出602nm的荧光。当钐的摩尔含量等于0.05,铋的摩尔含量等于0.02时，荧光玻璃的发光强度最强。因此，用这种方法制备的荧光玻璃可能能在半导体发光二极管的应用领域发挥一定的作用。
