Abstract:
1. A display device comprising: a cathode; an anode; a luminescent region disposed between the cathode and said anode; and a light-absorbing layer comprising i) metal nanoparticles, and ii) an inorganic matrix material, wherein the average particle size of the population of metal nanoparticles in the light-absorbing layer is from about 2 to about 20 nm and the metal nanoparticles have a particle size distribution not exceeding +/−75%; wherein said light-absorbing layer has a thickness of from about 10 to about 1000 nm, and wherein said metal nanoparticles are present in an amount of about 5 to about 50 percent by volume of said light-absorbing layer, and said matrix material is present in an amount of about 95 to about 50 percent by volume of the light-absorbing layer; wherein said metal nanoparticles are completely embedded in, or partially embedded in the matrix material.
