TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The nanocrystals comprise at least one of zirconium dioxide, hafnium(IV) oxide, titanium dioxide and zinc oxide. The nanocomposite has a refractive index of 1.6-1.9, preferably 1.8 at 400 nm. The nanocomposite does not include solvents.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The organic mixture comprises a mixture of poly(benzyl methacrylate) and poly(trimethylolpropane triacrylate) (TMPTA). The capped nanocrystals comprise at least one capping agent including 2-(2-(2-9-methoxyethoxy)ethoxy)acetic acid, 2-(2-(2-9-methoxyethoxy)ethoxy)acetic acid, methoxy(triethyleneoxy)propyltrimethoxysilane, 3-methacryloyloxypropyltrimethoxysilane, n-octyl trimethoxysilane, dodecyltrimethoxysilane or m,p-ethylphenethyl trimethoxysilane. The coating has a refractive index of greater than 1.8 at 400 nm. The substrate comprises glass, indium tin oxide, doped zinc oxide, gallium nitride, aluminum nitride, silicon carbide, poly(3,4-ethylenedioxythiophene) (PEDOT), poly(styrene sulfonate) doped PEDOT, polyethylene terephthalate, polyethylene naphthalate or doped poly(4,4-dioctylcyclopentadithiophene). The weight ratio of benzyl methacrylate to TMPTA is 7:3 or 75:25-65:35. Preferred Method: The method is performed in the absence of solvents. EXAMPLE - Acrylic monomers, benzyl methacrylate and trimethylolpropane triacrylate were mixed in a mass ratio of 70-75-25-30. 1-5 wt.% of benzophenone as photoinitiator was dissolved in the monomer mixture either by stirring or vortexing at temperature of 20-30 degrees C. The solution was then filtered to remove dusts and then added to dry zirconium dioxide nanocrystal and allowed to soak in the monomer blend until no zirconium dioxide powder was observed. Gently shaking the dried nanocrystals with the monomer blend was acceptable. Once all the zirconium dioxide nanocrystals powder was completely dispersed in benzyl methacrylate-trimethylolpropane triacrylate, the viscous suspension was mixed for 10-15 hours. The viscous suspension was filtered before processing the film and further worked up to give the nanocomposite.
