摘要：

Recently, there has been great interest in developing direct white-light phosphors for solid state lighting. Current commercial white light emitting diodes (LEDs) rely on complicated fabrication methods to produce white light. Utilizing magic-sized, white-light emitting cadmium selenide (CdSe) nanocrystals as a direct white-light phosphor eliminates the need for complex doping schemes and deposition techniques. Herein we report preliminary data representing the first elementary steps in designing and optimizing device architectures for building high-quality, highly efficient white-light emitting LEDs for solid state lighting.
