“…The main drawback of ZnS:Mn ACTFEL displays was the lack of full color capability. Multicolor displays can be made by filtering the wide orange wavelength distribution of the ZnS:Mn emission to green and red [ 39 ], but RGB full color is impossible ( Figure 2 ).…”

Sulfide-based luminescent materials have attracted a lot of attention for a wide range of photo-, cathodo- and electroluminescent applications. Upon doping with Ce3+ and Eu2+, the luminescence can be varied over the entire visible region by appropriately choosing the composition of the sulfide host. Main application areas are flat panel displays based on thin film electroluminescence, field emission displays and ZnS-based powder electroluminescence for backlights. For these applications, special attention is given to BaAl2S4:Eu, ZnS:Mn and ZnS:Cu. Recently, sulfide materials have regained interest due to their ability (in contrast to oxide materials) to provide a broad band, Eu2+-based red emission for use as a color conversion material in white-light emitting diodes (LEDs). The potential application of rare-earth doped binary alkaline-earth sulfides, like CaS and SrS, thiogallates, thioaluminates and thiosilicates as conversion phosphors is discussed. Finally, this review concludes with the size-dependent luminescence in intrinsic colloidal quantum dots like PbS and CdS, and with the luminescence in doped nanoparticles.

▪ Abstract New thin-film electroluminescent (EL) materials with blue and broadband emissions recently have been developed that meet the phosphor requirements for commercial multicolor and full-color EL display products. Improvements have been achieved in phosphor luminance, luminous efficiency, emission color, and aging characteristics. This paper reviews the latest advancements in red, green, and blue thin-film phosphors for patterned phosphor EL display applications, and broadband emission phosphors for the filtered white or color-by-white EL display approach. Focus is placed on the new EL materials and the composition modifications that have improved the performance of well-known EL materials.
