Semiconductor nanoparticle-based light emitting materials

A method of fabricating a light emitting device incorporating a light emitting layer comprising a plurality of light emitting beads dispersed within a host matrix material, each of said light emitting beads comprising a population of semiconductor nanoparticles embedded within a polymeric encapsulation medium, the method comprising:

• providing a dispersion containing said light emitting beads, an initiator, trimethylol propane trimethacrylate (TMPTM) and lauryl methacrylate;
• depositing said dispersion on a surface of a diffuser sheet to form a film thereon;
• annealing said film to produce said light emitting layer on the surface of the diffuser sheet;
• and
• placing the diffuser sheet over a light source such that the diffuser sheet is between the light source and the light emitting layer.
