基于高荧光CdS：Cu/ZnS量子点（QD）和YAG：Ce荧光粉的蓝光LED，制备了具有良好显色性的白光LED（白色LED）。再吸收的问题是克服了优良的光学性能和扩大的斯托克斯位移的量子点与波长大于470 nm的光的低吸收。
A white-light-emitting diode (white LED) with good color rendering index is fabricated based on a blue LED combined with high-fluorescence CdS: Cu/ZnS quantum dots (QDs) and YAG: Ce phosphors. The reabsorption problem is overcome by the excellent optical properties and enlarged Stokes shift of the QDs with low absorption of light of wavelengths longer than 470 nm.
