Phosphors for Field Emission Display: Recent Advances in Synthesis, Improvement, and Luminescence Properties

Field emission displays (FEDs) have been considered as one of the most promising next-generation flat panel display (FPD) technologies due to its excellent display performances and low energy consumption. Phosphors are irreplaceable components for FEDs. The exploration of highly efficient low-voltage FED phosphors is the focus of enhancing energy efficiency and realizing high-quality display. This chapter summarizes the recent progress in chemical synthesis and improvement of rare earth and transition metal ion-activated inorganic FEDs phosphors with powder and thin film forms. Discussion is focused on the modification of morphology, size, surface, composition, conductivity of phosphors, and corresponding effects on their cathodoluminescent properties. Special emphases are given to the selection of host and luminescent centers, the adjustment of emission colors through doping concentration optimization, energy transfer, monoor codoping activator ions, the improvement of chromaticity, color stability and color gamut as well as the saturation behavior and the degradation behavior of phosphors under the excitation of low-voltage electron beam. The authors also speak about the research prospects and future directions of FED phosphors and give some recommendations to facilitate the further exploration of new and highly efficient low-voltage FED phosphors.
