ABSTRACT
Phosphors are key materials used to convert electronic information into visible signals. The rapid development of various full-color, electronic, flat-panel displays (FPDs), including field-emission displays (FEDs), electroluminescent displays (ELDs), and plasma display panels (PDPs), demands timely discovery of advanced phosphors. The specific excitation media and operating environment of various FPDs require different sets of tricolor phosphors for desirable contrast, operation lifetime, and color properties. Although the photophysical process of phosphors under regular ultraviolet (UV) excitation is relatively well known, the fluorescent process of phosphors under excitation by an electron beam (FED, projection TV), charge injection (EL), or vacuum UV (plasma diaplay) are not well understood. The development of various FPD technologies is, to a large extent, limited by the lack of efficient tricolor phosphors.
