Abstract:

White light-emitting diode(w-LED) has the advantages of long service life, environmental protection, energy saving and high safety, which has basically replaced traditional incandescent and fluorescent lamp after development of more than ten years and is considered to be the new generation lighting source. As the core material of w-LED, fluorescence conversion material directly affects the performance of the device. Therefore, the development of high-performance fluorescent conversion materials is of great importance to further enhance the performance of w-LED devices. This review mainly describes the rare-earth phosphors and inorganic quantum dots which used in solid-state lighting device. We summarize the progress of the structural design, composition and photoluminescent tuning of rare-earth phosphors and typically introduce the design and photoluminescence tuning of chalcogenide quantum dots represented by ZnS, perovskite quantum dots and carbon dots used in w-LED. Finally, the future development including the opportunity and challenge of the fluorescent conversion materials for solid state lighting is prospected.

Key words: white light-emitting diode, rare earth doped phosphors, quantum dots, photoluminescence tuning
