Pulsed laser vapor deposition produces light-emitting silicon material

Investigators at Matsushita Research (Kawasaki, Japan) have developed a proprietary laser process for producing a light-emitting material made u¥of fine silicon particles. If the 10-nm-average-diameter

particles are covered with a thin oxide film and then subjected to an electric current, they produce a

reddish hue. The researchers say if particle diameters can be controlled, green- and blue-light emissions could be available. The three colors could then be applied to future high-resolution displays. The

particulate-based materials are fabricated using pulsed-laser vapor deposition in a helium atmosphere.
