白色led是由蓝色led与Sr3SiO5:Ce3+， Li+荧光粉和有机覆盖的CdSe量子点（QDs）组合而成的，其表现为二维超晶格。led的蓝色发光、荧光粉的黄绿色发光和量子点的红色发光结合在一起产生白光。合成的白光led表现出优异的显色性能和稳定的色坐标，抵抗正向偏置电流的增加（见图）。
White LEDs are fabricated through a combination of blue LEDs with Sr3SiO5:Ce3+, Li+ phosphors and organically capped CdSe quantum dots (QDs), which exhibit a 2D superlattice. The combination of blue emission from the LEDs, greenish-yellow emission from the phosphors, and red emission from the QDs generates white light. As-synthesized white LEDs show excellent color rendering properties and stable color coordinates against increasing forward bias currents (see figure).
