Three kinds of silicate phosphor thin films, emitting in the red-green-blue (RGB) primary colors, were fabricated by pulsed laser deposition: manganese and lead doped calcium silicate (CaSiO 3 :MnPb) for red color, manganese doped zinc silicate (Zn 2 SiO 4 :Mn) for green color, and cerium doped yttrium silicate (Y 2 SiO 5 :Ce) for blue color. A good correlation was found between photoluminescence intensity and film crystallinity and surface morphology. Introduction Phosphors are widely used in emissive displays. However, all currently used phosphors still need considerable improvement such as in lower current saturation, high efficiency, and better chromaticity [1]. Oxide phosphor (including silicate phosphor) is more chemically stable than sulfide phosphors under high Coulomb loading. As a matter of fact, silicate phosphors such as Zn 2 SiO 4 :Mn have been used in CRTs. Electroluminescence (EL) device have also been made from these same silicate [2]. In all the display application...
