White light-emitting diodes (WLEDs), as key infrastructure, play an important role in the field of lighting and display.In the past few decades, many methods were developed to prepare WLEDs.A common strategy is to use blue LEDs to excite yttrium aluminum garnet (YAG) phosphors and generate composite white light, which is now the main technology for commercial lighting.In 2014, Nobel Prize in Physics was awarded to Nakamura et al.for their contribution to blue LEDs[1,2].
