Color conversion in LCD displays

A method comprising:

• preparing a hybrid sol-gel precursor formulation from:
• an ESOR (epoxy silica ormosil) solution comprising TEOS (tetraethyl orthosilicate), at least one silane precursor other than TEOS, and GLYMO ((3-Glycidyloxypropyl) trimethoxysilane);
• a DURS (diurethane siloxane) nanoparticles powder comprising isocyanate-functionalized silica nanoparticles and ethylene glycol, wherein the silica nanoparticles are maintained as nanoparticles in the formulation;
• and
• a transition metal alkoxide matrix solution, and
• mixing the hybrid sol-gel precursor with at least one RBF compound;
• and
• spreading the mixture and drying the spread mixture to form a film.
