Abstract
The present disclosure provides a high-refractive index acrylic formulation embedded with sub-30 nm metal oxide nanocrystals. The formulation is solvent-free, low-viscosity, injectable (among other film deposition techniques) and produces high-refractive index, high transparency nanocomposites for a variety of optical applications including OLED lighting and display applications.
