An improved color-converting photoluminescent film that provides visible light emission in the red to green portion of the visible spectrum when excited by blue light. The color-converted photoluminescent film of the invention is patternable and has improved luminous efficiency and stability and is suitable for use in electroluminescent displays. The film comprises a mixture of a clear UV curable resin and photo-initiator which does not absorb blue light; and fluorescent pigment particles, wherein a molecular additive is optionally provided in to either or both of the pigment particles and curable resin. The mixture is screen printed onto a substrate to form a film and UV cured.

Color-converting photoluminescent film

A thin film phosphor for an electroluminescent device, the phosphor being selected from the group consisting of thioaluminates, thiogallates and thioindates having at least one cation selected from elements of Groups IIA and IIB of the Periodic Table of Elements. The phosphor being activated by a rare earth metal and containing oxygen as a partial substitute for a portion of the sulphur in the crystal lattice of the thiogallate, thioindate or thioaluminate. The phosphor is a single phase homogeneous compound and provides improved luminance stability. An electroluminescent device comprising the thin film phosphor is also described and methods of making the phosphor of the invention.

The present invention is a low pressure physical vapor deposition method for the deposition of multi element sulfide thin film phosphor compositions for electroluminescent devices where a thermal source comprising a polysulfide compound provides the source of sulfur species for phosphor film deposition and/or annealing. The method is particularly useful for the deposition of phosphors for full color ac electroluminescent displays employing thick film dielectric layers with a high dielectric constant.
