Research progress of green luminescent materials for lighting and displays
New solid-state lighting and display technologies have remarkble advantages of high brightness, high luminescence efficiency and environmentally friendly, which have become a technology with great application prospects for high-end lighting and display in the field of indoor and outdoor lighting, automotive headlights, laser TVs, etc. As the core material for fluorescent conversion lighting and display, the performance of green luminescent material undoubtedly determines the optical behavior of the device. However, under the operation of high-power density laser, the temperature of green luminescent material increases sharply, which leads to the decrease of quantum efficiency and luminescence attenuation, and seriously restricts the application of solid-state lighting and display technology. Therefore, different physical forms of green luminescent material came into being. In this paper, the latest research progress of green luminescent material for laser display is reviewed. The control strategies of the properties of green luminescent material, such as powder, ceramic, glass and film, in term of thermal stability, full width at half maximum(FWHM), color gamut and chromaticity parameters are summarized systematically. Finally, the challenges of green luminescent material such as luminescence efficiency and device packaging are discussed, and the research progress of green luminescent material for lighting and display is prospected.
